I’m pretty sure everyone has an Ikea Raskog trolley, right?
I use one for storing all my tapestry butterflies and yarn for my current project (the other is for sewing supplies).
Since I use butterflies rather than bobbins, I also store them in separate bags with details of which yarns make up the butterfly … essential when I use so many gradients of grey!
Do you have a Raskog trolley? What do you use it for?
