tell her she needs a hobby of her own!
my hubby is so good about being (supportive) when i am in the sewing room but there are times when he wanders down the hall to say..."how's it going?, or.. are you about ready for a break?...or...are we having dinner tonight? :-D or are you coming to bed?...
after awhile they just learn...this is how it is...it is what quilters do...
she will get used to it...just ease her into it...and take a break once in awhile and spend a few minutes in her world... :thumbup:
