My friend bought me a roll in the US awhile back.... it was the pits...kept separating....BUT...... was about 1/20th of the cost that we pay for it here for light heat n'bond...... after a few frustrating uses...I plunked it back in it's plastic sleeve (not sealed) & put it in the deep freeze & it has been great ever since...it sits in a tub in my sewing room, and I've been very happy with it since. I decided to try this as at some point I had read about thread drying out & getting brittle & this was the cure....anyway, it seems to have worked for me...maybe it will help someone else.
