Has anyone here ever crocheted a queen size bed spread?

4. For a project like this, a bulky yarn in stripes

would work just fine, in my opinion. I'd also vote for a synthetic yarn, as many of them are quite good. Caron Simply Soft yarn is one of my favorites for afghan projects. Right now I'm making one using two strands held together, so in effect you get a bulkier yarn.

If you decide to do the two yarns held together thing, you can get some very interesting tweedy looks as you do the stripes.

A finer yarn, especially the sorts used to make doilies, would simply not work to do an allover large piece, I don't think. Something like that would be at great risk for sagging or stretching, and that kind of yarn is best done as squares that are then crocheted together.
