Sewfisticated. Theres one in Dorchester and one in Somerville (Twin Cities Plaza).

We have a fabric store in Arlington that has trims (it's called Fabric Corner, Mass Ave & Mill Street). Also PlayTime in Arlington Center (Broadway) an independent arts & crafts store has things like feathers. If you go to PlayTime, head downstairs.

Both of these are indies, and real town treasures.

Oops, sorry, I just saw that you say in you are in Boston for the day...you probably aren't shlepping out to Arlington---I can't help you with Boston proper.

Gather Here in Cambridge has fabric!

I love Fabric Corner!! I need to plan for a few hours there ha

Yes! If there’s nothing here in the city proper, I’ll be going to sewfisticated in Somerville on the way home. My favorite shop to pick up lace fabric.

What a great shop! When my kids were little I would get organic cotton there all the time 💜

There's Van's Fabric in Chinatown. They specialize in high-quality Chinese & Vietnamese silk brocades, but IIRC they have some other stuff.

I would say Chinatown must have something

Not anymore. I think there are one or two specialty silk import places handing on, but that's it.

Playtime Inc. in Arlington has a lot of trims on the basement floor. Hop on the red line T to Alewife and hop on the 350 bus and get off near Broadway.

This is a little outside the box, but the Garment District has costume supplies and also a by-the-pound clothing option on certain days. I always thought maybe I’d make something out of secondhand clothes.
