They are finally available:
Project bags from Alte Künste!
Took me ages to find an ethical supplier of organic cotton bags!
But here they are: GOTS certified, the print is organic as well & no child labour was involved!
The bag has a size of 25x30cm (9.8×11.8″) with a cord to close at the top. About 5 skeins of yarn fit into it (there are 2 more skeins jammed into the bottom of the bag to have those 3 in photo peak out of it).
The project bags are available in the shop. Each order over 100€ will get a bag for free.
