Hi Gazza,
when I listed a lace curtain panel I noticed there was no specific category for lace or sheers, just fabric, I think there should be a subcategory for lace and sheers since they are very different from regular fabric curtains.
I would list it like this:
Home&Garden/Curtains&Blinds/Curtain Fabric
Home&Garden/Curtains&Blinds/Curtain Lace&Sheers
I don't think that the Curtains&Blinds/Net Curtains is the same thing as Lace or Sheers. Alot of people wouldn't be looking in that category for lace panels.
Thanks :-)
