Hello Gazza. I think Sewing & Embroidery would benefit from having at least one other subcategory: tools. Possibly other categories as most sewing people use them, although this might be too detailed:

Crafts & Sewing/Sewing and Embroidery/Tools (e.g. tape measures, specialty items and pressing aids)
Crafts & Sewing/Sewing and Embroidery/Scissors, Shears & Cutters (e.g. Olfa rotary cutters)
Crafts & Sewing/Sewing and Embroidery/Hand Sewing Needles, Machine Needles, Pins & Pinholders
Crafts & Sewing/Sewing and Embroidery/Sewing Boxes and Baskets
Crafts & Sewing/Sewing and Embroidery/Elastic, Zippers & Hardware

Thanks.
