Prym - knitting calculator & counting frame

This knitting calculator and counting frame by Prym is an essential tool for when you are knitting or crocheting all kinds of clothes! At first, you should knit or crochet a bit bigger than 10by10cm piece with the selected needle and yarn. First, the amount of stitches and rows per 10cm is calculated using the counting frame. (Lay the ruler on your knitted piece and count the rows and stitches). Then the red knitting calculator's slider can be set to the calculated value on a scale of 8 to 49 stitches per 10 cm. A viewing window directly shows the stitch and row count for lengths from 1cm to 100cm. The stable plastic gauge allows you to measure or check needle sizes,  between 1.5 and 10mm.
