1) this list isn't entirely complete, but it's a start.
2)Since many yarns are ok knit at a half stitch per inch difference than what their label may say (depending on what you're making and what type of fabric you desire), you may want to check out the options at a gauge either side of how we have them listed. For example, the label on Cascade 220 suggests that it can be knit at 5/in on a US 7 or 4.5/in on a US 8. We've listed it under 5/in on a 7 because that's my preference for most sweaters, but for someone else, or even for myself for a scarf, knitting this same yarn at 4.5/in on an 8 may be preferable.
3) we haven't listed Lace/scarf/shawl yarns here, you can them out by clicking on those highlighted links
4) some of the sock yarns might be great for gloves, scarves, wristlets, and lightweight cardigans etc, so if this is your project in mind, you might want to check out the sock yarns too!
