I saw some pillowcase dolls in catalogs from
Mary Maxim and then in Herrschners. These may not be what you want but all I know that are available at this time.
From the 90's your best bet is Ebay ... and price is what they are worth to you most likely... I would expect to pay more than the 90's cost as they are hard to find now. I have some of them packed away, but am not looking to part with them. Have Amanda in progress now.
Good luck with your search.
