More doilies -- I keep cranking them out!

I decided to try a doily in Number 3 crochet thread (equivalent to fingering weight yarn) to see how many rounds would create what size doily.  This is the Sternbluten pattern, available on Ravelry.  It is 90 rows deep, and measures 25" across.  So, by my calculations, I will have to find a pattern of about 300 rows to make a tablecloth for my 60" dining room table to have some overhang.  And I will have to put some extra lengths on my interchangable needles!

It is photographed on my stovetop.  Not the most pleasant backdrop, but the best I could do at 11 p.m.
