Besides Pine Tree in Salem and Candlelite in Chelmsford (my favorite home away from home because of their friendliness) there are few more in the Lowell,MA and Salem,NH area:
Bits n Pieces - Rt 38, Pelham, NH - sort of on the way to Salem,NH
Sew Together, Rt 38, Tewksbury, MA - other side of Lowell from Bits n Pieces
Also other 'nearby' shops:
Quilters' Way, Concord, NH
Quilters' Common, Wakefield, MA
Hope you will be able to get to some of them.
I believe they all have websites if you want to check them out.
Have fun!
