I have 2 flax bobbins, 1 silk bobbin, 1 bobbin that's "identical" to my favorite, and 2 others. The whorl sizes are totally different from what I already had - I need to sit down and figure the ratios and all, but yea! I have 9 bobbins for my Norwegian wheel!!
I need to sit down and play with them...but I'm 1/2 done with Christmas present #3, and I want to get it DONE. Friday has been slated "get to know the new bobbins" day.
