I've never been known for my organizational skills. In my crafting/sewing room, I usually have a general idea where any given tool or material is, but my ability to find anything in particular hinges on the mental image I have of the last time I saw said item. I use my embroidery and cross stitching supplies often enough, however, that they're generally to be found towards the top of any given pile of accouterments.
I almost always use wooden hoops, though I do have a Q snap frame that is growing on me. I do most of my stitching on thrifted fabric, often using vintage sheets or pillowcases that I find at Catholic Charities. I started out using plastic bags strung on giant sized jump rings to organize my floss (DMC), but as you can see, it has started to pile up in a heap in a plastic tray instead.
I always like to have a portable project ready to tote along with me in my purse, so for that I use this great linen zipper pouch that my mom got at a quilt shop hop at some point and didn't want. (I know, right?!) I love this little pouch--it's Moda fabric and features a print of a pair of shears. It's just big enough to hold whatever small cross stitch or embroidery project I'm working on, embroidery scissors, a good sharp, irreverent pencil, a fine tip Sharpie marker, a seam ripper, and plenty of skeins of floss.
The tracing paper I use a lot for transferring patterns. I like to use pictures from vintage children's books or coloring books, or even images on the web. Once Eliot found a great old picture book about superheroes from our local library, and I couldn't resist this Wonder Woman. She was begging to be stitched.
So pulled out the tracing paper, traced the image lightly with a pencil, then flipped the tracing paper over and traced the reverse side with an iron on transfer pen.
Then I just ironed her onto some white fabric and started stitching away. I'm planning on cutting away all but a thin white outline and then maybe adding a yellow star to her left. Not sure yet.
I love the metallic gold thread for her lasso, but it is such a pain to work with. I think I need to get my hands on some Thread Heaven, as I hear that makes working with metallics a bit easier.
