Filet crochet has been on my "to learn" list for ages now..
this is my first go at making my own ..
started out simple..
with time allowing I hope to get more complex designs going although I plan on keeping them to a smaller size..
we'll see how it goes..
I then added a few leaves a vine and a rose, after putting a single crochet overlay around the cross..
I used a size US B1/2.25mm hook and size 10 crochet cotton thread.. each block is 3 dc's ( last on counting as the first in the next ).. it can be used in other counts.. however you like.. I had learned this method with a bookmark I had just done so gave it a whirl.
