Hi Erin
Hairpin lace?

Just the name sounds intimidating. Although it is beautiful, I sure wouldn't frustrate myself to attempt it. I hope it clicks for you soon, and you finish that project successfully.
I'm so glad the mattress pad had a good home.
I get the numb/pain combo, I don't know why they don't cancel each other out.
I'm sorry your knee is hurting so much. Please rest yourself.
