In my OWN person opinion I think it would be a great idea.
Just set "boundries" on what he can and cannot use.
Take him on a "fabric" buying trip for his own stash (small to start with).
At this point I would LOVE to have SOMEONE (anyone including my hubs)
to share my love of fabric and quilting with. But who know if that DID happen
if I would like sharing or not.
I KNOW I would NEVER NEVER NEVER let him use my NEW baby. But I would
let him use the other Brother emb/sewing machine.
Of course I say this because I KNOW my hubs would never in 100 years much
less a million years say "yes" to learning how to quilt.
Heck I can't even get my daughter (I have 3) to get interested in quilting, much
less sewing. The 2 oldest does crochet, and the youngest does latch hook (when
she is not studying at college).
