DIY St. Patrick’s Day Baby Onesie

Here’s what you need to make your own:

  • glitter heat transfer vinyl
  • Silhouette cutting machine (or scissors or an X-acto knife if you’re doing it by hand)
  • baby onesies
  • iron and ironing board
  • a hand towel

Cut out a shamrock shape from your heat transfer vinyl. If you’re using a Silhouette cutting machine, remember to cut out a mirror image because heat transfer designs go on backwards. For a shamrock it doesn’t matter that much, but if you want to add words to the onesie, make sure they are mirrored before you cut them out!

Once the shamrock is cut out, peel the extra vinyl off of the plastic backing, then place the shamrock plastic side up on your onesie.

Heat up your iron, lay a clean hand towel over the shamrock, and press the hot iron down onto the shamrock for 45 to 60 seconds. Gently peel up the plastic backing; if the shamrock comes up with it, put the iron back on for another 15 seconds or so.

Once the shamrock is fully stuck, peel the plastic backing off, and you’re done!

    Adorable! Any suggestions on where I can get the vinyl? Looking for a mainstream store as I need for Saturday so do not have time to order online. Thanks!

      Hmm, I always order my vinyl online, so I don’t know where to get it in an actual store! I know Michaels and Joanns don’t have it, but maybe Hobby Lobby? Sorry I can’t be more help!

      Actually Melissa, now that I think about it, you may be able to get the Cricut brand vinyl at JoAnns or Michaels. I know JoAnns sells the Cricut machines, so I’d check there first!
