I never get rid of thread, so I guess you could say say I collect it. I don't buy extra thread but do seem to attract it.

Right now I have a ton of embroidery thread most of which came as a bonus with other purchases. If I turned my machine on now, I think I could go several years without stopping except for bobbin fill.;)

The other thing I seem to be attracted to right now are purse patterns.

anything quilty

quilt magazines and patterns

Magazines, books and patterns.

Books, hundreds of books! (quilting, cookbooks, home decorating, watercolor painting, gardening), rulers, and teapots

thimbles -- i collect them from all the states we have visited, i have some from countries around the world (friends and relatives bring them back) and some old ones found at flea markets. i have about 80. and, they don't take up much space.

Thread and rulers

I never thought about my books and magazines being a collection but yeah those. And I have a few vintage sewing machines including toy ones. My pincushions are what I think I collect. Other than ones others have given me all mine are made in Japan vintage animal ones. Or the ones with the little men around them. I love the colors. Thimbles that have come with sewing lots I got off of ebay. Vintage lace and doilys. some sewing boxes, Eeyores. Rocks yep them too, Everytime someone travels anywhere I ask them to bring me a rock .I will never get to travel to these places so this is having a part of the places. I have one from Ireland that my DD's best freind brought me back, From Brazil, Rome, and other places my brother has traveled.
Hmmm looks like I need to stop collecting something. LOL

Patterns! Patterns! Patterns...and books with Patterns!

Books. Yes and dust of course. But you weren't asking about that one...
