A rope bracelet - reminds me of making friendship bracelets back in the day. My right second toe used to go numb because I'd hook the end of the bracelet over it, and then knot embroidery floss for HOURS.
Some of these are not as full of things I'd have to buy (googly eyes, craft paper, etc) so that's why I'm pinning it. Are there really moms with time to glue tiny googly eyes onto foam monsters for their two-year-olds?
