Gather Here and Make Something
This store probably has the cutest variety of fabric prints I have seen in Boston but the problem is the prices! OMG they are so high but it so hard to pass them up. The cottons start from about $9-15 a yard and the organic cottons start at $16 a yard. I went during a sale so it wasn't as bad but you really need a special project to go there. This store also has a huge amount of knitting and crochet supplies and yarn. One really cute thing about his store is that they also have classes which you can sign up for online and they also offer a free knitters brunch every Saturday.

Friday 11 a.m. to 7 p.m.

Windmill is my go to fabric store inside of Boston. When I was in college and didn't have a car this was the easiest place to get to. You can walk there from Downtown Crossing or from Boylston T station. This place has a great variety of fabrics and the price are pretty reasonable starting from about $4 a yard from cotton. The prints may not be as modern or cute as Gather Here but for the location and prices I say it is totally worth the trip.
