Lucky you! I started making shirts for my kids years ago before Target was flooded with a t-shirt for every holiday. It's become a bit of a tradition. Mainly just for Valentine's and St. Patricks at this point, but that doesn't mean I won't take full advantage of some silly reason to make custom t-shirts for the the gang.
Mostly I make them because I luurrvvee when we match. It's my favorite! When we can all line up and wear the same shirt - it's so stinking cute! It's like a Hanna Anderson ad, but for t-shirts. Since Target has yet to see my vision, I make them myself.
The most challenging part of these is cutting out the template. I use freezer paper for the template because it cuts out really easily and you can iron it on to the shirt so it sticks and forms a perfect template. You can use sticker paper or stencil paper too - freezer paper is a cheap and easy option!
May these shirts bring you and your little leprechauns much luck!
