Drat! I forgot to mention that really nifty s hooks can be made out of bits of wire or wire coat hangers.
Clamps are available if you cut them off of the plastic clothes hangers that come with clothes from various places. Some of those places have plastic clothes hangers they are throwing into the recycling bin and will give to you with no charge. (Also very good to use when binding a quilt, those plastic clamps.)
I quit.
