Hi, I use Metro Thread, it's an online store. They prices are extremely low. Under a $1.00 for a 1000 m spool.
They have stabilizers too. I bought stabilizer from them to use for my 'trial' stitch outs. Pre-cut blocks, that fit
frame. Makes life slightly easier. There customer service is outstanding. I had some thread where I could not find
the free (start) thread, they took the color numbers and without any other questions about it, sent me out new
spools!!! Just so that you know, I do not work for this company...I'm just trilled I found them!!!
