Flexible stitch holders like it sounds like what you need, *DO* exist. Here is a link to some that can be ordered online, and I've had no trouble finding the same thing in several of my local yarn stores. I think that Michaels Crafts probably has them too.

I wish I could make local recommendations for you, but I don't know what crafting resources are in your area. Anyway - I hope the link helps, and that you can get a few of these inexpensive but VERY handy items, soon!
