I love this invitation design! I designed this for my son's 4th birthday party awhile back and I have to say I think it's my favorite so far. The invitation is gender neutral and also looks very pretty in pink. The rocket logo looks great on the kids' tee shirts with their names monogrammed on them. To transfer the design onto the tee shirt I used Wilton easyimage transfer iron on sheets and printed them on my inkjet printer. I followed the iron on direction that came in the box with the iron on transfer sheets and before I knew it, I had twelve adorable keepsake shirts for the children.
