I like to use varigated thread for my Linus quilts as it saves changing thread for each one I make. I made the mistake of choosing a spool of varigeted Aurifil thread at my local Bernina Dealer /fabric store/ etc. etc. The price wasn't posted. Before I got to the cash register I decided that two would be better than one. I had a hard time hiding my surprise when the bill came to a little more than $25.00 for the two items. OUCH!! I will say that there seems to be a lot of thread on those spools. I have done four or five Linus quilts, loaded at least 6 or 7 bobbins and the first spool doesn't even look touched.
