… I just really need to find time to sew!

Lightweight white linen from https://www.fabric.com/
One of the online fabric stores I’ve used before sometimes has good prices on linen. I don’t often shop there if stuff is on regular price, but a while back I saw they had lightweight linen on for about $4/yard – they only had 19 yards, and I bought all 19 yards!
I think that this is the same lightweight linen I have used in the past to line my red and gold Italian gown, the black and gold brocade Italian overdress, lined the skirt to my green Italian petticoat, and made a navy Viking underdress with. (Probably a few more things too). White linen will be even MORE versatile I bet – since I’ll be able to dye it too if I need a certain colour.
