Well, DUH! Why didn't I think of a bookmark? Thank you. I like it!
Yup, by the time PayPal and the post office get through with me, a $2 donation becomes a $1 donation. Maybe I should raise the price to $3.
I have a whole big container of "zip stops" that I bought at a gargage sale. They're all different styles of those little spring-loaded fasteners like you get on the hoods of jackets or laundry bags, to tighten the strings. I could chainstitch cords to put through those and sell them cheap to anyone who might need to keep things together where a rubber band might rot away or be tacky-looking. Maybe I'll work on that idea, too.
