You can easily add some twill tape and make a quick child's apron
or you can add some bias tape (remember this post about how my pal transformed those Ikea cupcake dishtowels into a stylish apron using I have to say's tutorial?) for this version I just added some 10mm elastic inside the bias tape for the neck strap. I also shortened the tea towel by about 3 inches.
These aprons were used for a little Valentine's baking party. Stay tuned and have a great week!
P.S. there are a number of tutorials out there using dishtowels for half-aprons, the possibilities are endless: Lipstick and Laundry has a half apron tute or this post on Squidoo has a great round-up.
