It is available in both UK and US, both versions are available to download. I think this is easier than having two listings, as it means if someone accidentally picks the wrong version, they can easily remedy.
It uses 1 x 200 g ball of Bendigo Classic Wool, and works up fairly quickly. Great project for someone who has mastered the basics and looking for a next step project.
If that isn't enough value already, there are also instructions for an alternative version of the square, one of the prototype versions that was too pretty to leave out.
Thanks for having a look! If you do make a bag, please let me know by adding a project on Ravelry, tagging me on Instagram, or sharing on my Facebook page!
