I used a quarter for the gumballs and a CD & note card for the gumball machine. (I added Heat N Bond iron-on adhesive to the back of the material before I cut it)
I pined the gumballs, then sewed them in place.
After everything was sewn on I ironed it for the extra strength and support.
My very happy client! Paisley said "Gumballs for me?! Oh, thank you mommy you are so thoughtful!" Then she asked if I could make a shirt for her friends at daycare. So I think it is safe to say this shirt passed the test!
