Here are the hardanger curtains in their embryonic state. Two yards of 32-count Belfast linen (36"x55" each), 10 balls of #8 pearl cotton, and 5 balls of #12 pearl cotton. I don't really know how much thread I will need, but this is the basic #B5200 white thread and doesn't have a dye lot that needs to match. If I need more (unlikely?) then it's readily available, and any leftovers will certainly be used on other projects.
There's so much potential in this little pile of supplies.
I did a little charting today to work on the design, and zigzagged around the edges of the linen to prevent fraying.
