It sure came in handy to buy so many because Chris broke 2 before completing this one. This required much concentration and hand and eye control for him! The activity came with little squares of tissues that they wrap around a point needle (but not) type thing and dip it in glue then punch it into the foam.
I found them in the vacation bible school or summer craft type section. I will be keeping an eye out for these babies this summer (as they are originally only $1) and end of summer because .50 is always awesome!
