Here in the Studio, we have a customer, Jodi. She's a great gal, great knitter, but she has one terrible habit. Dumping lots of yarn in a bag and dragging it all around New York City until it becomes a tangled mess:
She came in the other day and our trusty Michelle helped her with her mess. I told them I call this picture
"The Tangler and the Untangler (or friends don't let friend's tangle their yarn)"
If this is a problem for you, and you're in the NYC area (or stopping by on vacation this summer), stop by the Studio and pick up a project bag (or two) to keep your yarn organized, OR read some of the "tips of the day" from customers on LionBrand.com for useful storage ideas.
