These handy tubes from Bellwether Yarns are great to use instead of waste yarn or long circular needles to hold you live stitches - either when you want to try something on (I just clicked too - try-on tubes!) of if you just want to hold your stitches and keep them flexible. They come in a cute tin with a QR code that takes you to this YouTube link so you can see how to use them!
With one cord at 150 cm and two shorter cords at 75cm each.
