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.

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.

Make sure that the color you use shows up against your phone.

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.

Make sure that you are using clear silicone. You can find it in home improvement stores. It comes in a syringe. [11] X Research source If you can’t find cornstarch, look for cornflour. You can also use potato starch instead.

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] X Research source

If the case is dusty inside, wipe it down with a damp cloth.

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] X Research source

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] X Research source

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.

Make sure that the glue is clear and glossy. Add a piece of fabric on top of the lace for a layered effect.

You can find washi tape in the scrapbooking section in an arts and crafts store. Try a chevron pattern for something more interesting.

You can lay the tape down horizontally or vertically. Do not cover the sides of the phone case.

You can also use patterned, cotton fabric instead.
