I think it's a little early - it might make her uncomfortable and obviously you're uncomfortable or you wouldn't ask. How about a 25% off discount on any item she wants.......then be ready to give her prices for a table runner, mug rugs, lap quilt and queen quilt.
I've been going to my hairdresser for 7 yrs and would consider a quilt as a gift.............except she and I bartered...I don't pay for hair cuts/perms and I'm making her a quilt.......She'll have to do my hair for 20 yrs at the price she charges!!!!!
