i have a couple i use every day- couldn't live with out them...they are made from felted wools, one is a little book style with 6 pages-looks like a little notebook- a cover and a velcro tab closure...it fits perfectly in a hinged tin i use- along with my stork embroidery scissors & needle threaders.
the other one is more a wallet style with a pocket for a spool of thread, felt (tabs) to hold needles- threader's, pockets for scissors, ect- it folds like a tri-fold wallet. there are many many different types, styles of needle keepers- people who do hand work love them-use them all the time.
