I just finished piecing the spokes of 47 dresden plates for a king size bed. I get such a childish sense of accomplishment from emptying spools of thread when I sew.
I just used up 1000 meter of Aurifil! Wow, I sure sew a lot! (Patting myself on the back).
I was the same way in school. Feeling like I must really be getting somewhere when I filled up my school notebooks, or a pen ran out of ink.
