Tatting in progress! with a 2-bobbin tatting shuttle

This tatted edging is in progress. I'm working on it with this lovely dubble bobbin shuttle.

I'm trying to tatting a very long edging and I'm thinking to working on it all the summer.  This edging I'm tatting with two differents kind of thread. The blue one it's cotton nr. 50 and the other one it's cotton nr. 20. This motif  is my own design.

Happy tatting summer to every one. Thanks !
