I see that people are wondering about how to use their scrap yarn.
One pattern has become very popular this summer: Leftie by Martina Behm.
There is a new group ano Ravelry for scrap yarn ideas, Scraps of Joy.
My Octopetala scarf is another idea.
Sanna Vatanen has some nice ideas in her book "Stricka och Virka med restgarn". As far as I can see, the book is availble in Finnish and Swedish. On Ravelry here.
Granny squares are well known, of course. Here's another nice square that needs very small amounts of yarn for the circles. Le vesinet by Sigrun Hugøy. I tested the pattern a couple of years ago.
And there's the the beekeeper's quilt, of course!
What's your favorite way to use scrap yarn?
