This is handy and pays off big time as you seam sweaters and such. All those pieces of yarn that you cut when you’re working on the machine?–snip a bunch of them into ten to twelve inch lengths and keep them handy. Collect different colors so you always have a contrast marker. Then, next time you’re knitting something that will be seamed together, hang a piece on the end stitches every 20 or 40 rows; the number isn’t important, the consistency is. When you’re seaming pieces together, these markers eliminate any question as to whether you’re staying even. Very helpful when seaming Fair Isle because changing colors puts different tension on your stitches and makes them tricky to match up if they’re not marked.
