This bag can be made from leftover or regained wool yarn, but
of course you could buy yarn for this purpose as well.
If you use a felting yarn like Lana Grossa »Feltro« (100 m/ 109 yds to 100g), you’ll work with a single thread. Calculated material needed if worked in Feltro, single color (For a special color design like stripes etc. you might need more yarn):
Size M: 300 g plus some extra yarn for crab stitch edge = 350 g
Size L: 430 g plus some exta yarn for crab stitch edge = 500 g
The bag pattern is suitable for beginners.
If you like, you can finish the bag with a row of crocheted crabstitches. After knitting, the bag is felted in the washing machine.
The pattern comes in 2 sizes: Size M 38 x 25 x 10 cm or 15 x 10 x 4 in after felting, or L 45 x 30 x 12,5 cm 0r 17½ x 12 x 5 in.
2 bag handles are needed and a tapestry needle.
