For the rainbow shoes:
Step 1: Use blue tape (I used masking tape here, but either will work), to mask off the stripes. To make the stripes equal, measure the length of the shoe and divide into as many colors as you want to use (I used 6).
Step 2: You can paint three colors at one time.
Step 3: Once the colors are completely dry (don’t short cut it), slowly take off the tape.
Step 4: Lightly tape over the previous painted colors and paint the remaining three colors.
Step 5: Wait until it’s completely dry to remove the tape.
Step 6: There’s a chance that some paint might come off with the tape. Simple patch it over with paint.
For the green shoes:
Step 1: Carefully paint the entire sole green. Use blue tape around the edges to make a clean line.
Step 2: Make sure it’s completely dry before removing the tape.
