I stitched these pink and cream boucle zipper-top bags to use for all your needlepoint accessories, or as a small bag.  Lined with a neutral beige polished cotton, with a silver-tone metallic nylon zipper.   

You can use this bag as is, or you can stitch a small needlepoint canvas to it! I stitched through the fabric with my machine pretty easily--it's thick, but it should be doable.  

Measures about 6 x 6.5 inches.  This is the smallest size in the last image.  Please note that this is a good size, but I don't think you'd be able to easily fit an 8 x 8 inch canvas on stretcher bars in this bag.
