Yay Joyt!! Congrats all around!
That roving is SUCH a pretty color. Too bad on the first spindle cracking; you might try taking the hook out and sliding the whorl up to the top edge of the dowel then putting in the hook again. Regardless of the crack, it should hold well, being braced by the whorl.
Anyway, I also LOVE your new spindle! Nice choice!
Don't toss the other one away though, it's handy to have 2.
