Lookie what came for me today
It's the high speed flyer kit I ordered for my Louet wheel. The kit included a high speed flyer, three fat core bobbins, and a spare drive band for much less than I've been able to find them elsewhere.
Since I chose the free (slow) shipping option I really didn't expect these to show up until sometime next week at the earliest. In them meantime, I started spinning one of my precious Grafton Fiber batts Sunday at my fiber guild meeting.
