So here are the results of the crochet bowls I made with the Feltable wool that I talked about here.
I made up the orange/yellow round bowl first and then the wider mouth blue/green one. I'm really happy with the results of the felting and wanted to talk about it a bit :)
The rounder bowl went through the wash three times ( if I remember correctly ) I have a front load machine that heats the water itself. I can not manually adjust the water level. The second and third times a couple of pairs of outgrown kids jeans went in with the bowl and both washes were 2 + hours at 90deg. Each wash cycle it went through did improve the felting.
The shrinkage was significant so I decided to try and hand felt this one and see if it made a difference.
I went through various warm hand washes creating friction by rubbing and using a small amount of water with detergent. the fabric was becoming more felted each time and the shrinkage was significantly less than when using the machine method. However as I am impatient, once my knuckles were blistering from the wet wool friction I threw it into the hot wash cycle I mentioned above to finish it off. It then shrank in line with the size reduction of the other bowl. I understand there will be shrinkage as a part of the felting process but did not expect it to be this much.
For now I have two small colourful felted bowls, my fingers have healed and I still have lots of lovely bright wool to felt with. I will most certainly have another go at it.
