This was done in DMC Perle Cotton 5 in colour #413. Curds and Whey is a pattern from Mary Konior's Tatting with Visual Patterns. This would be MK6, that is pattern #6 that I have tatted from this book.
This one was made using DMC Perle Cotton 12 in colour #818. In size 12 it looks more lacy and extra long. How different the pattern looks in different sized threads.
