I made those bags in the last couple of weeks. This one is also after a pattern by Two Old Bags but the yarn is Evilla Artyarn 100% wool. I can't imagine knitting something else with it. It's soooo scratchy but perfect for felting. I LOVE the color though.
I have a collection of old buttons from the time I was still sewing clothes and did some serious quilting (not that I needed many buttons for that).
You can see the difference between before and after felting. I had to let it through four wash cycles and was thinking of a fifth. It's still a big bag, hence the name I guess (Bucket Bag)
It looked like a feed sack in the beginning. For the picture I've stuffed it with sock yarn. I might make a lining for it still. Have to see about some fabric. It would have to be done by hand. My sewing machine is "out of order". But I think things like bag linings have to be done by hand anyway. This green bag will replace my summer bag I made a while ago, when it get's near the end of summer.
