Young boys and girls grow out of their clothing quickly. So when you see a T shirt that is getting a little to short, it's time to make a Story Shirt!
Read a short book that has strong imagery or memorable characters. Tell your kids that if they read the book aloud to you (lend a hand if needed) their reward will be to use special markers (a lot of kids get excited when they are allowed to use Sharpies!) to design a T shirt based on their reading.
After your kids have finished the book, allow them to color the almost-outgrown T shirt however they'd like. Kids LOVE to detail and wear their own clothes. Let them wear the shirt for the rest of the night or save it for a trip out to your favorite park or play date.
It doesn't matter how accurate the drawing (especially on a t shirt) - the freedom to color on the shirt was just a route to get them reading. Praise them for the final product, even if Tim Gunn would object! And of you give your kids the opportunity to show off their shirts, you'll encourage them to read again, because there are always more shirts to outgrow!
If you prefer a blank canvas, go to the boys' underwear section of your local Target and pick up a multi-pack of undershirts, or visit AC Moore during a sale and stock up.
Don't forget your sharpies! A variety pack with 6 - 16 colors can be bought at any local office supply store.
