At spinning group I plied up the next skein of red BFL - I had already spun up the other two pieces of red BFL before going to the group. Then I decided to work on the Galaxy roving. I split it in two lengthwise, without checking to see if they had the same weight. When I split it in half again in the middle of the length, I noticed all of the turquoise was on one end, so I made sure to spin them in opposite directions - that way turquoise would be on each half.
But the point is, I spun about 3 ounces of it at the group, then spun the last ounce and plied it at home. And when I got to the end of the 175ish plied yards, I had only about 6 inches left on one bobbin.
See that fuzzyish piece toward the lower left, lying on the bottom end of the bobbin? (It looks kind of like a shadow, but it's fuzz.) That's the end of one single. The vertical line is the remainder of the second single - it ends before the top of the bobbin.
Plus, I didn't get sunburnt (except for a small piece, less than a square inch, that I somehow missed) - last month I put sunscreen on my arms but not my neck, and I painfully regretted it for weeks.
