12 month onesies baby shower gift idea

Create your own 12 month onesies

  1. Print out your design on white fabric transfer paper. Make sure you print the mirror image. What prints should look backwards to you. You can find the printable numbers here for a boy and girl version.
  2. Cut out your design and prep your onesies by ironing out the kinks your onesies.
  3. Place your cut out face down on the front side of the onesie. Make sure you read the directions that come with your white fabric transfer paper. In my case it told me to hold it there for 2 minutes total. I didn’t want to hold it in the same spot the whole time therefore I made circles and continuously moved the iron around while maintaining good pressure. Let it cool down before removing the backing (this may differ depending on your type of transfer paper)
