The blanket has been hanging out on the back of the couch during this last year too. Norbert favors it and the flannel quilt that I sewed a couple of years ago to lay on top of. Those diamonds were tricky to line up and there might have been some swearing involved since it was Brandon's idea.
I've used the dryer to help dry fiber and handspun yarn - it came with a dryer tray so the stuff can lay on the tray and have all the heat and none of the agitation that causes felting. Love it!
With the Lizard Ridge Blanket and the coffee spill it was the first time I was able to use a washer setting - Wool. I first fixed some of the snags, darn dog nails grabbing strands and pulling, then popped it into the washer with a smidgen of detergent, then walked away. I didn't want to watch - chicken I know. ;-)
Twenty minutes later I came back to get the washed blanket - looked awesome! A clean and bright again. Then I looked at this wet wool blanket and was so not going to go through the air dry process. So looked at the dryer to see what it could offer me. There's a 'delicate' cycle but there's also a 'super delicate' cycle. Score! In went the blanket and it did take two times through the super delicate cycle for the blanket to get dry, but it didn't felt at all! Love it!
