I used to use any backdrop to hide my HA. It seems this isn't the case now? Is there a way to completely hide your HA?

Only certain backdrops can completely hide the HA. Most newer ones and recently revamped ones can, but older ones (for example ) actually have an HA-shaped hole in the artwork because the HA base wasn't a separate layer in the wardrobe for a long time, so that was the only way to use a background with your HA. You just have to make sure you're using a background that doesn't have the cutout

Ah! OK! That makes complete sense. Thank you so much!

If you want to use a partial background or something like that you can use the . If you use it with old backgrounds that have "cutouts" you'll just get a white blotch, but it can be helpful with some designs. Examples below, with and without vanishing cream: by Lypsyl by Lypsyl

Thank you! This is very helpful!
