Siesta Plastic Thread Organiser

I ordered these from the US for my niece in England. I bought one there a long time ago and love it - could not find anything similar here. They are sturdy, keep my thread organized, and are much easier to use than holes punched in a piece of card as the thread slides easily. Since I write the symbols for my cross-stitch on them with pencil it can be erased and reused for a different project.
