What wearable craft screams "Summer?" Tie dyed t-shirts that's what.
I am in charge of planning weekly activities for the 12-13 year old girls at church, and last week they squealed and shrieked with excitment when I told them we'd be making tie dye shirts. I didn't think anything less than Justin Bieber himself could get that kind of a reaction, but this did it.
I bought a kit from Michael's craft store (40% off! thanks to a coupon from my mother-in-law) and everything was included in it--dye, gloves, rubber bands, instructions. Everybody did their own thing and everybody had a blast. I was going to make a tie dye tutorial for the blog, but seriously, my tutorial is this: go buy the Tulip brand kit from a craft store.
Now I can't stop thinking about buying another kit to make tie dye shirts for all my friends--it was that much fun.
