Here's what I got in about an hour on Saturday:

A lot of it is thread, but I was able to go longer without having to do joins than I remember doing before.
Debbie suggested I try pre-drafting to a heavier weight so as to avoid the thread issue, so I did that for an hour on Sunday:

Obviously I've got a long way to go before I have actual yarn, but I can see I am reaching one less celebratory milestone: having no more space on the spindle.
Seriously, what do I do with this stuff? Should I rewind it onto some sort of spool and keep going or leave the break and spin a few cones together at the joins when I finally run out of fiber, or what?
