First step was to get paint. I went to Hobby Lobby and was surprised to see a much smaller selection than I'd hoped for. They had TONS of puff paints, but I didn't want that texture in my finished product. The paint I would've purchased was $5/container... and I just didn't want to spend that much money. I ended up with what is actually screen-printing paint, for $2.99/container. Much better, and cooler colors to choose from. I also grabbed some generic craft/glue brushes. My brushes were $1.50 for six, so about $.25 apiece... I guess it's not as great of a craft to me if it costs a significant amount of money, so I like to keep things inexpensive.
I really thought I had freezer paper at home but alas, all I had was waxed paper. Not the same. SO, my second trip out was to WalMart, where I found a massive $5 roll of the stuff. They must have been out of generic and smaller rolls, because I didn't notice a cheaper option.
I created a "Jesus Loves Me" design back at my house and printed it out on normal paper (I wondered if it would be possible to just print directly to the freezer paper... maybe I'll experiment with that another day). I then transferred this design onto the freezer paper by tracing first with a pencil, and then second with an exacto knive to create a stencil. Make sure that your design is face up on the matte side of the freezer paper. You want to be able to iron the stencil to your tshirt before you paint, which means glossy side should be down.
The cutting out of my design took the longest, maybe because I don't have the steadiest hands or maybe because I've never done this before, but more than likely because I was eating Ben and Jerry's ice cream at the same time.... now that, my friends, is multi-tasking. Once I was satisfied with my stencil, I ironed it onto the onesie I was decorating. I made sure to put a piece of cardboard between the layers of the tshirt first, so that I could be ready to paint right away.
I painted in my stencil carefully. It would have been easy to tear off a piece of the freezer paper with my cheapo brush, even though it was ironed on. It was best to paint inwards toward the center of the design. Another thing I'll do next time is use a different brush for each color. Rinsing brought extra water and you'll see in my final product that it may have been what caused the bleeding. A crisper design could be attained with a more dry brush.
After the paint dried - the tube said 24 hours, but I decided overnight was long enough (I've heard that it's OK to use a hairdryer to speed up this step) - I just peeled off the freezer paper to reveal a neat design! I had been worried that the freezer paper would leave some kind of residue on the t-shirt, but it didn't! The smaller pieces (like the white spots on the "e"s) needed the help of an exacto knife to come off. Last step: use a rag between the iron and the paint to heat set the design.
That's all she wrote!! I had so much fun making this. I have four more onesies and already have an idea for my second freezer-paper craft :)
Here's my second onesie! I love the way this one turned out. I wish the circle border had come out better, but hey, it's pretty cool anyway.
