So during the week I finished the armwarmers. They are extremely functional. I got some bargain bin merino wool ($2.99 at Spotlight). I wasn't sure how much I would need but it took less than 2 balls, altho I did get a nice olive for some stripes. I guessed 50 stitches, plain and purled my way to a rectangle. Then stitched up the sides allowing a wee hole for my thumb. Excellent. Bit of a hobo look with a t-shirt - so long sleeves is probably a better way to go. What every blogger/Etsy-er needs (well those currently in cooler climes).
