Hi hi

I'm stuck in bed and starting to work on embroidery. All of my threads are wound on a spool. They seem to be general purpose threads as far as I can tell. Right now I'm folding them into four parallel threads and using that, doubled up. (Each stich is eight threads.) Some work better than others.

I'm slowly running out and will need to replace them, but I don't know anything about thread. The normal embroidery-specific threads don't seem to come on spools, which I would greatly prefer. They also have different sizes and I have no idea what's that about.

Basically:

Help! What is a good general purpose brand that comes on a spool? It doesn't have to be embroidery specific, but should be adaptable to use in embroidery.

Thanks!
