Here is my daughter's shirt:
It just says,"Today I Am" and then it has boxes that he/she can place a little check or heart in so we know if he/she is "Batman" or a "Fairy" or "Spiderman" or a "Princess" or best of all, him or herself! To make the shirt, I just printed out different fonts from our computer, made a stencil from freezer paper, ironed it on and painted!
For the check and heart, I just used sticky velcro and put a little square in the middle of each box (I used the soft part of the velcro for the shirt), and one little square on the felt check or heart that I cut out.
And, that's it! A quick and easy way to make a really fun shirt!
