Sock Loom 2 Braid Board Regular Gauge

Can you also use lighter weigh yarn (such as sock yarn) on this loom or does it only accomodate worsted as specified on front of box?

Would this product be easy to use for a blind adult?

How many hours to make one sock? Let's say one color, no patterns. I know it'll vary by person, but any answers appreciated.

I see there are 3 different american knitting board sock looms. would this be the best one to start with? (i've never made socks on a loom before.)
