My daughter has been asking for a rubber band loom for her birthday, and even though it is a few months away I picked one up on sale. I also grabbed a couple refill packs.
I might just give it to both kids to share early, and figure something else out for her birthday. I don’t know how many times she has taken the bracelets (and put them back together) that she has been given by her friends.
I found a few sites with ideas for rubber band looms
I’m sure there are more out there but this will get her started whenever I give it to her. (and if I just give it to her she needs to share with her brother too)
