Bear with me, please, but I don't understand why anyone buys prewound bobbins. A simple calculation --- I checked on prices at the Connecting Threads website. Here's what I found:
Prewound - 82 yds ea for 12 bobbins = 984 yards at $9.99. This calculates at $.010 per yard
Spool of thread - 1200 yards at $2.49 = $.002 per yard
Cone of thread - 5000 yards at $9.99 = $.0019 per yard
So a cone of thread will net you 5 times the amount of bobbins compared to prewound.
OR -- another way....you can save $50.00 by buying a cone and winding the thread yourself.
Am I missing something??? More money to buy fabric!!!!!
