Making a Yarn Keeper

I am not a knitter, but I saw an idea for another use that might work. Could you use old socks to hold the yarn? By using one sock per color, they would not roll around or become tangled. Then all the socks (colors) could go in a box, basket, whatever is handy. Since I'm not a knitter, I don't know if the yarn would be held too tightly inside the sock to be used easily. I'll be interested in any feedback.

Coke bottle would work but they no longer have the plastic cups on the bottom. Ive used empty coffee cans and empty ice cream container, shoe boxes. You don't have to get fancy an regular box will do. You just need to be able to keep the yarn from getting tangled and rolling all over the place.

The soda botttles work great. Instead of cuttting a hole in the side for the yarn to go through, take the plastic cup off of the bottom of your bottle, put your yarn in the bottle running the end of your yarn through the neck of it then put the cup back on the bottom of the bottle to hold your yarn inside.

How about cleaning out 2 liter soda bottles or gallon milk bottles. Punch a hole on one side, just large enough for the yarn to go through. Just a thought.
