I hate having yarn leftover. When I had various mini-skeins of this left from my Twinkle cardigan. I tried making a hat (below), but the bulky yarn was too stiff so it was frogged within 24 hours!
So I chose a crochet lace pattern because it was easy and it was flexible enough to use up all the yarn. It's the Queen Anne's Lace Scarf pattern but I couldn't understand the crochet instructions and improvised a bit
I crocheted a total of 30 motifs... with very little yarn left! :)
