Form-Flex woven fusible interfacing is my all-time favorite interfacing and it is often sold out when I go to the fabric store. But today I scored a whole bolt. I almost left without buying anything (amazing!), but decided to check if they had this in stock, and yes, it was available!
I use a lot of interfacing, but don't need all 35 yards to myself right now, so I have it listed some in my etsy shop. Check this section if this listing is sold out, or send me an email or convo and I'll post a reserved listing for you.
If you are outside the US let me know how much you need (2 yard minimum) and where you are located, and I'll send you a shipping quote.
