How to Make a Cell Phone Case

Cell phones come in many shapes and sizes, and finding a case to fit your phone can sometimes be tricky and expensive. Luckily, making a custom cell phone case is easier than you'd think. You can easily make a case at home using a hot glue gun or some silicone and cornstarch. You can also make a simple slip cover out of felt. If you already have a plastic case, then why not decorate it to make it stand out?

Things You Should Know

  • Create your own phone case using hot glue, silicone that you can buy from a home improvement or crafts store, or felt.
  • You can buy many of these items cheaply, but the steps to make the cases functional are a little more intricate.
  • Decorate a plastic case that you already have with puffy paint, dimensional fabric paint, or lace.

  1. Making a smooth case is difficult with hot glue, so most people choose to do patterns, such as swirls or mandalas. You can free-hand the pattern, or you can trace it. If you want to trace it, do the following: [1]
    • Trace your phone onto a sheet of paper.
    • Draw your pattern using a black marker. Make sure the design touches the sides.
    • Cut out the template along the outline.
    • Tape the template to the back of your phone.
  2. Cut a sheet of parchment paper that's about twice the size of your phone. Place your phone on top, with the screen facing up. Wrap the paper over the side edges of your phone, then secure them with a piece of tape. Wrap the top and bottom edges, and secure them with tape as well. [2]
    • Wrap your phone as tightly as you can.
    • Make sure that the phone is turned off first to prevent overheating.
    • Make sure that you are taping everything on the front of the phone.

  3. These will be your guidelines so that you don't accidentally cover them with hot glue. [3]
    • Make sure that the color you use shows up against your phone.
  4. This also includes the speaker and mic holes as well. If you cover them up, you don't be able to use your phone properly. [4]
  5. Make sure that you make them nice and thick. Also, make sure that you avoid the buttons and sockets. [5]
  6. Again, hot glue is not the best medium to create a perfectly smooth case, so your best bet is to make a texture of pattern. Whichever you choose, make sure that all the lines connect to the sides of the phone as well as to each other. [6]
  7. You can simply draw a thin line around the front of the phone, right next to the side edge. You can also make a series of tiny dots instead. This will give your case a lip and help it stay on your phone. [7]
  8. Once the glue has hardened, peel it off of your phone. Remove the parchment paper from the phone next. At this point, it would be a good idea to test the case on the phone. If there is any glue covering a button, socket, etc., then you can cut it away with a craft blade.
  9. Once you are happy with the case, take it off of the phone. Paint the outside with nail polish, then let the polish dry. [8] If you want the case to be a solid color, you can use spray paint instead. [9]

Making a Silicone Cell Phone Case

  1. Cover your counter with plastic wrap, parchment paper, or wax paper. You can also work on top of a marble counter or a glass sheet instead.
    • Try to work in a well-ventilated area. Silicone can have a strong odor.
    • The silicone used in this method is not the same as hot glue.
  2. Pour some cornstarch onto a smooth counter or into a glass bowl, then squeeze some clear silicone onto it. The measurements don't have to be precise; you just want to have more cornstarch than silicone. Plan on using about 5 tablespoons (50 grams) of cornstarch and 2 to 3 tablespoons (30 to 40 grams) of silicone. [10]
    • Make sure that you are using clear silicone. You can find it in home improvement stores. It comes in a syringe. [11]
    • If you can't find cornstarch, look for cornflour. You can also use potato starch instead.
  3. You don't have to do this, but it a good way to make your phone case look more interesting. If you don't do this, your phone case will look white. You use a few drops of liquid dye, liquid watercolor, food coloring, or acrylic paint.
  4. You will need to knead it about 20 times or so. You won't pick up all of the cornstarch, which is normal. The dough may look crumbly at first--just keep kneading!
  5. You can do this with a rolling pin, a glass, a wine bottle, or even a spray paint can. Keep rolling until you have a sheet a little larger than your phone. It should be about ⅛ inch (0.32 centimeter) thick.
  6. Make sure that your screen is facing upwards, and you have equal amounts (or close to it) of dough sticking out over each side.
  7. Slide a paint spatula under the dough, then lift it up and fold the dough over the sides of the phone. Smooth out any creases or wrinkles; try to be as neat as possible. [12]
  8. Flip your phone over and dust it with cornstarch. Use a stamp to indent designs into it. You can also use cardboard cutouts instead to create your own, unique designs. Lift the stamp away when you are done. [13]
    • If you want to make a quilted design, let the silicone harden for about 10 to 20 minutes, then dust it with cornstarch. Use a knife to make cross-crossing diagonal lines in a diamond/quilted pattern. [14]
  9. How long this takes depends on the type of silicone you used and the weather condition. It may take just two hours, or it may take 24 hours. Once it is dry and solid to the touch (you can't dent it), pull it off of your phone.
    • If the case is dusty inside, wipe it down with a damp cloth.
  10. Cut it about 7 millimeters away from the side edges, and 1 centimeter away from the top and bottom edges. [15] Alternatively, you can cut along the indentations caused by the seam between the phone's screen and case.
  11. If you were to look inside your cell phone case, you'd see little indents caused by the camera, flash, buttons, and sockets. Cut all of these out using a sharp craft blade. [16]
    • You can also carve a rectangle or trapezoid into the top and/or bottom edge for the speaker instead of cutting out a slot. [17]
  12. You can apply more raw silicone on top if you want to, then smooth it out with a paint spatula or popsicle stick. [18]
  13. Choose a color that goes well with your case. Metallic colors, such as silver, work especially well! [19]
    • You can make more shapes out of silicone separately, let them dry, paint them with nail polish, then glue them to the case with a drop of clear silicone. [20]

Making a Felt Cell Phone Case

  1. If you want a thicker phone case, use two pieces of felt instead. They can be the same color or contrasting colors. [21]
  2. Place your phone on top of the first piece of felt. Trace around it using a ½-inch (1-centimeter) border. Cut the felt out, then use it as a template for the other piece(s). [22]
  3. Make sure that all of the edges and corners are aligned. If you are making a lined case, with two different colors of felt, choose one color to be on the inside, and the other color to be on the outside. [23]
  4. You only need to pin the bottom and two side edges; leave the top edge open. Try to pin the felt as tightly around your phone as you can. The fit will be snug at first, but it will eventually loosen up. [24]
  5. Use the pins as a guide as you sew. Your seam allowance will vary, depending on the thickness of your phone. You can do this on a sewing machine or by hand. [25]
    • If you are doing this by hand, consider using embroidery floss in a contrasting color.
    • If you are doing this on a sewing machine, backstitch at the start and end of your sewing.
  6. Try to cut as close as you can to the stitching, about ⅛-inch (0.3 centimeters). [26] For a more unique look, use pinking shears instead.

Decorating a Plastic Cell Phone Case

  1. A clear case will work the best for this, but you can use a colored one depending on the design that you pick. Once you have your case, choose one of the decorating ideas from the list below.
  2. Buy some puffy or dimensional fabric paint from the art store. Use it to draw designs on the outside of your case. Let the paint dry completely before putting it onto your phone. Great design ideas include dots, spirals, zigzags, and chevron. [27]
  3. Trace the front of the case onto a piece of lace. Cut the lace out, then coat the inside of the case with decoupage glue. Press the lace into the glue, then coat it with another layer of decoupage glue. Let the glue dry, then cut out the camera hole with a craft blade. [28]
    • Make sure that the glue is clear and glossy.
    • Add a piece of fabric on top of the lace for a layered effect.
  4. Choose a solid-colored case in a color that you like. Buy some washi tape in coordinating colors or patterns. Wrap the tape around the case, including the sides. Be sure to leave some space between each piece so that the case's color peeks through. Cut out any socket/speaker/camera holes with a craft blade. [29]
    • You can find washi tape in the scrapbooking section in an arts and crafts store.
    • Try a chevron pattern for something more interesting.
  5. Lay down strips of washi tape over the back of a cell phone case. Make sure that the edges touch and the patterns align. Flip the phone over and trim away any excess tape hanging over the sides. Cut out the camera hole as well. Finish off by coating the outside of the case, include the sides, with clear, glossy, decoupage glue. [30]
    • You can lay the tape down horizontally or vertically.
    • Do not cover the sides of the phone case.
  6. Trace the case onto a piece of scrapbook paper, then cut it out. Coat the inside of the case with clear, decoupage glue. Press the paper design-side-down into the glue. Let the glue dry, then cut out the camera hole with a craft blade. [31]
    • You can also use patterned, cotton fabric instead.

    You could glue a small mirror on it with hot glue. They probably have what you'll need at a craft store, like Michael's or Hobby Lobby.
