My resolution to not buy any new fabric until using up the old fabric has been absolutely destroyed by Lincraft's ongoing closing down sale.
It's not my fault, I just can't resist flannelette.
Also all the assorted $5/m mystery fabrics from China are now $2/m and while most of these are clearly some kind of plastic I found the last of a bolt which seemed to not be. Got it home and burn test confirms either viscose or pooossibly cotton. By the feel and drape (and cost!) honestly I'm pretty sure it's viscose but if anyone knows a test to distinguish the two for sure, let me know.
