If the Excorsized cottage is coming back this year, I plan on getting it, along with the witches and scarecrow furnishing packs currently on the PTS. I like the idea of creating a halloween/witches festival themed house with scarecrows, jack o lanterns and everything.
I would also like to request more of these seasonal/holiday houses, especially of the large/medium category, which is actually furnishable, and not like the huge empty manors.
How about a New Life festival house. Could be a snowy cottage somewhere in Skyrim, complete with a small outdoor garden area and indoor area to make a nice midwinter fire and a yule banquet. Make a furniture pack with some special New Life ornaments and decorations as well.
Jester's Festival have gotten a few pieces of furniture as well, like the boxes, the flags and the pavallion. A small outdoor area with lots of room for cherry trees and a festive jester's pavallion and some special, funny furniture in a furniture pack would be excellent as well.
