I just noticed that Connecting Threads is having a sale right now. You get $5 off a $35 order, $15 off a $70 order, or $25 off a $100 order. The promo codes are listed on their website. You get free shipping over $50, too. I just bought a bunch of fabric (which I needed like a hole in the head! LOL!), and the discount is good even on their clearance prices.
It says the sale runs through 4/9/18.
Just thought I'd enable ... er ... share!
Edited to add: It also says their batting is 30% off right now. Since the discount above is good even on their clearance prices, it may also work on the batting!
