crochet hooks

[momonlongisland]

Hi,
I've accumulated many crochet hooks thru the years and unfortunately some of the more newer "colorful" plastic ones aren't marked with sizes. Anyone have any clue or link to match them up to a size? Thanks

I saw in a catalog not long ago a guide that had holes with the sizes so you took your hook, put it in the guide to know the size. Wish I could remember where I saw it, if I run across it, I'll let you know.
