I have been working on a “fulled” project. In this case it is knitted items that are then partially felted through the process of hot water, cold water and agitation. The process shrinks the item and makes it quite dense and compressed.
I have discovered that there seems to be no science or guarantee with fulling, quite honestly it is one big science experiment that will drive you insane if you let it. For example, I have now tested 4 different yarns plus about 6 different needle sizes, a couple of different wash/agitation methods and tested dyeing before fulling and after. This has been a project of testing for almost a year. This has produced numerous failed test swatches, that are now known as “Barbie blankets”. Yes indeed the Barbie doll house has been furnished nicely with my rejects (but our daughters are thrilled!).
I think I have finally figured what works best. Strangely the knit is so big and sloppy in the beginning, yet this is the combination that shrinks down the tightest and most compact. The best wash/agitation method turned out to be the washing machine which is awfully convenient as our household with five children means the washing machine is ALWAYS running.
The funny thing about this whole process of figuring out fulling is the fourth combination I ever did was the one that gave the best results. Somehow I was convinced it could be better so I kept knitting and fulling more and more versions and only seeing disappointment. I guess there is something to be said for the saying “quit while you are ahead”.
