The Herdy Rucksack pattern is available only as a Knit Kit from The Herdy Company. The backpack is suitable for adults and children, measures approximately 30cm x 30cm when complete and can be ordered in six different colourways.
The rucksack has a drawstring and flap closure, and the shoulder straps are easily adjustable to suit the wearer.
If you wish to make a second rucksack, Herdywool can be ordered direct in the UK and now in the US too!
A photographic tutorial to help with the making of this knitting kit is available on the designers blog http://theauldwoollyalliance.wordpress.com
