I've been experimenting.
Once up a time my sister bought home a crazy crochet bag from Nepal. Apart from the fact that she should have bought more of them, the work in it is fabulous. I have envied and studied that bag for years now. It is old and shabby and yet she still wears it wherever she goes. It is made up of crochet squares.
I experimented with regular wool trying to get the basic pattern of the block. I am a very new crochet person so I really did not have a clue what I was doing. To make matters worse I have discovered that Americans and the English use different names for the same stitches. What a pain.
Anyway the regular wool just looked ordinary. The wool in her bag is made up of all sorts of blends of fibres.
I solved the wool problem in a dream. This is quite normal for me. I wake up and know what to do. About 30 years ago I studied how to do tapestry weaving. It's an awesome textile skill. I did about 3 short courses with the Australian Tapestry Workshop and still had, locked away somewhere, a fair amount of their reject wools that I just couldn't bear to part with. My loom is still hidden in my brother's cellar. I will have to rescue that one day.
Anyway, I found the wools and started making them into little 3 ply bundles and began making the crochet blocks. I have made enough blocks for the body of the bag. They are all sewn together so now I need to stretch them as they are a bit lumpy. A wooden frame and some water spray should do the trick.
