I am frequently asked where I get my fabrics. I do buy a lot of notions and cute prints, especially knit and woven fabrics, locally. In the past I used Yahoo Groups to buy most of my soaking fabrics, PUL, and snaps. I haven't been active in these groups for a very long time, so I cannot assure anything about them currently. Here are my favorite sources:
Sew It Seams Coop (This was my main resource for cute printed PUL, CuddleDry Microfleece, cotton velour and sometimes even matching cotton knits.)
Buy-the-Yard-N-More (Another great group for a wide variety of fabrics and supplies.)
PUL Purchasing Power (Great group for buying PUL from Fabrite.)
Notion Supply (This is the group where I order my snaps. Her snap press packages are surprisingly affordable and shipping from China is faster than you'd think!)
Or visit the main website at Assunta Store for the website associated with the same people who run the yahoo group. I still order snaps from Assunta store and I also highly recommend their one-size pocket diapers. While you're there, be sure to read their "About Me" page!
The Fabric Fairy (Retail store where I order knit fabrics when I have a hankering for something new.)
Also be sure to check Hyena Cart and Etsy. I have found excellent deals on fabrics, even lots of fabric, on both of these sites!
