These t-shirts probably won't be the most exciting thing under the tree, but Lucy has been wanting a peace sign shirt for awhile and she loves anything with a dachshund on it, so hopefully they won't be a complete disappointment.
Usually, I use Wonder-Under or Heat 'n Bond to do appliques. Those products work well and make appliqueing really simple, but sometimes they can be kind of stiff. So, this time, I experimented. On the peace sign, I only used a glue stick. On the dog, I used an iron on silky stabilizer on the wrong side of the t-shirt. I got a few wrinkles with both methods, but I think they worked as alternatives to iron on appliqueing.
