This is one of the few store-bought ready-made kits I've done with the kids. I thought it would be a good introduction to sewing for the kids (who frequently ask me to teach them "how to make Nubbins"!)
The 2 main issues with this problem with this project were... #1: that the kids had issues with learning how to make a knot in the thread...and #2: White glue is extremely frustrating for kids to work with when working with felt (white glue only really works with paper). The glue kept soaking into the felt and the kids were getting frustrated because they kept pressing on the pieces or picking the whole thing up, and felt pieces and/or googly eyes would come off. But ultimately they learned that the project needed to be left alone to dry and I think they really did enjoy it, despite their glue-frustration.
