New England is full of wonderfully productive quilters, I'm sure you can find a quilting guild close by and they can direct you.
And just because you've never quilted *yet* doesn't mean you need never learn! Making quilts generally requires only a straight stitch - nothing fancy - and the ability to cut a straight line with a ruler and a rotary cutter (looks exactly like a pizza cutter
). Every quilt shop has beginning classes and most guilds have someone who will take a complete beginner under their wing. Wish I were closer, I'd love to mentor you so you could finish your mom's quilt yourself. What a lovely memory.
