These double-ring markers will become an essential tool for your knitting projects that require increases, decreases or patterns every other row.
At the start of a round, thread the needles through the metal ring (the uncoloured one). Then knit a single row, usually all knit stitches.
When you reach the next row, slide the coloured ring onto the needles, which reminds you to make a decrease, an increase or any other pattern every two rows!
There you go – no need to check which row you’re on anymore; the colour reminds you to do the special row! Thank you, little double marker!
