I decided to purchase the plastic snap on lid containers for my in-progress or ufo's, one reasons why, we have 5 dogs and 4 cats (my 2 barn cats are in and out, mostly in during the winter) and bags won't keep out the hair! I look to see if they are on sale every time I go to Meijers to get groceries or even a script. Needless to say, I am getting a real stock of plastic boxes - the shirt size boxes - and almost all of them have something in them! So, I'm avoiding being a bag lady but I do want to someday be Gladys, the grumpy old lady on the greeting cards!
