The problem with knitting from the outside end first is that the yarn cake would bounce around when I pull new yarn from it during knitting. I don't know how or why, but the cake would bounce so vigorously that it would end up at the other end of the room. Even when I put it in a knitting bag, it would bounce out of the bag!
Here enters Yarntainer. Put the yarn inside a container, and there it stays. Good idea. But I didn't buy one. One thing is bothering me - how do I remove the project from a Yarntainer before using up the yarn, if I need to? If you have seen said gadget in person, you'll know that there is no other opening in the lid, except the hole in the middle. Besides, most of the photos of Yarntainers show you knitting needles tugged inside ... but if you pay enough attention, you'll find that those are idle needles without projects on them. Unless you have very little yarn left inside the container, my bet is there would not be enough room to put the project inside.
So, I know the concept of Yarntainer, not the gadget itself, is what I want. A thread in Knitter's Review (but I couldn't find it anymore!) solved my problem:
Next time, I'll have new project to share with you. In the mean time, everyone stay cool. :)
