I’m having the hardest time finding lace-weight cashmere yarn. Any sources? Anyone know who’s selling any? Elann has fingering weight cashmere yarn. Could I substitute it in a lacey scarf pattern? Thanks! 
Ebay has some:
Yeah I was looking for lace weight. Do you think I could sub. fingering weight for lace weight in a lacey scarf?
Thanks! 
I’m sorry I thought they were the same, what is the same as lace weight?
Well anyway here’s some lace on ebay.
Handmaiden has a gorgeous laceweight silk/cashmere blend:

Go to ebay and go to Colormart UK store.
I’ve bought from them and they are very good - they have laceweight and other weights on cones and skeins.
They have an ebay store - its all in US $ prices so the market they aim at is the US rather than UK (though they do sell to the UK).
The store is at:

and they currently have 134 laceweight cashmere items
