I am the same way. Nothing as big as a loom but so many other must have craft items. My hubby says I just like to "experience" different things. Boxes of scrapbooking stuff, totes filled with candle making items, a few closets full of photography necessities, and won't even get started on my baking addiction; which is just as bad as my fabric/quilting addiction.
I love all my hobbies and the older I get the more time I have to devote to them, but yes I have a hard time focusing on just one.
