I take four different sewing classes and each has a project. I use the Yazzii organizers (2 of them in different colors) to hold the threads and small tools needed for each project (small scissors, circular stencils, etc). I use a separate bag for the fabrics and large tools (ruler, rotary cutter, etc). The Yazzi organizers have eight clear zipper pouches that allow me to display all threads in my project (and I can see their color and id number) as well as separate the threads by type. other pockets store small thread scissors, common needles used for that project, stitch ripper, sewing pencils etc. The organizers make everything easy to find and cut down on time “searching” for the proper tool or thread color. They are also sturdy and well designed, come in several different colors and have zippers so that everything stays in the right place. Well worth the price!
