I love craft activities that are made from things that would otherwise be binned. We had a package the other day and inside was this piece of foam, so we made ghosties from it. I drew the outline of the ghosts with a biro and Ebi-kun cut them out. It was quite a challenge to cut the foam but he stuck with it, even though I could tell he was having a hard time.
Then he stuck on some goggle eyes (a craft box must have, you never know when you need goggle eyes). We left them to dry whilst we nipped out to run some errands, when we came back Ebi-kun use a needle and threaded cotton through the top, I tied the knots.
And then he hung them on the tree (Ikea bargain, ¥10!) Whoooooooo
Sorry about the picture, it is supposed to give off that spooky feeling LOL.
