I'd like to start by saying that the decal is designed for Avery (or any brand) iron-on transfer paper, made for 100% cotton. You can apply it to one of your own already existing tee shirts, or buy an affordable plain, light-colored one. This kawaii face decal can also be applied to your pillow case, linen tote bag, etc.
So here is a step by step video tutorial from YouTube. I hope it's helpful.
The tee decal is only 27 cents CAD (you're not imagining that) on Etsy:
And as always, I would *love* to see you wearing your finished project and post it to your own social media with #Kawaii365
