Are you charging extra for the babysitting?
I have to Crochet on the Double or knit fur because I can't see it at all.
At least with Cro-Double I can pull it out until it's one stitch.
If I lost a knitting needle I'd probably have to get out the Opti-visor and "un-knit" a row to get it back on.
My sister had an ADULT over who found a strand of yarn. She pulled and pulled and pulled and pulled before she realized what she was doing.
Luckily my sister only crochets so she just lost work and didn't have the joy of threading back onto a needle.
I only have a dog to worry about, but it is the fur he wants to play with. Luckily he tends to steal them out of the bag (I'm still missing a skein of purple fur).
