There are quite a few websites. I have typed in "embroidery stabilizer" and got several responding websites, or you can go to Ebay and do the same.

Good luck with the hunt!

Hugs, Bonnie

try the zipperstop they also have a store on ebay

try worldweidner for stabilizers, free shippping

So far I've had to get the zippers at one place and stabilizer at another to get a good price.

I have been getting my zippers at zip-it on etsy and some of my stabilizer from World Weidner.

The best price I have found for zippers is sewtrue.com

Jan,
I have purchased most of my supplies from www.allstitch.com, and feel they are reasonably priced. Their customer service and quick delivery is the best! As far as zippers, I second "Bevintex" on recommending www.zipperstop.com.

I haven't ordered anything in quite some time but my first picks are always: sewtrue.com and threadart.com
I also used to love to go to stanssewingsupplies.com for all my zippers and parts-but he has become kind of expensive over the last few years

You can get both and so much more at the attached sites. I've been using Homesew for many years, and they are, by far, the least expensive sewing supplies store that I've ever found!! Be sure to check out their trims bags. It is a grab bag idea, but worth far more than they charge.
