Here is my this evening's work: crocheted cloves edging for white linen handkerchief.
crochet hook is soooooooooooooooooo tiny ,you almost can't see it.
It's 0.6 mm. Smallest available I think!
Thread is mercerised cotton 60.
I do this kind of work sometimes ,but could not make bedspread with sooooooooooooooooo tiny thread...
Absolutely honour old lace makers who did really great work with even finer thread!
