It's hard to keep things contained where you want them, but I think you have a lot less yarn than I do. I have wide, deep shelves around three sides of one room at above the door height plus two lower shelves on two of the walls and they're all crammed with yarn. Then there are about a dozen bags of oddments there isn't room for on the shelves. The rest of my craft stuff is packed in boxes in several rooms and I have a big ottoman full of Aida for cross stitching. >.<

Yay, well done for finishing the scarf, and I'm glad your blocking board and pins are working for you! Now you can finish your mittens.
