Here' another option. I read this in another thread in this forum......Boston/Cambridge Fabric Stores...
calicoon suggested Zimman's in Lynn. You can take the Newburyport/Rockford Line Commuter Rail out of North Station, to Lynn. 2/10ths of a mile from the Lynn Station is Zimman's. calicoon says this about Zimman's:
"I know it isn't in Boston or Cambridge, but Lynn is accessible by bus, and by rail (?) There is a great old fabric store there....um...Zinma n's? that my friend and I used to go to when we lived there. I bought some beautiful blue marbled-look cotton for curtains, so it had to have been cheap"
80 Market St
Lynn, MA 01901
