That is a Farbenmix pattern called Vida. Farbenmix is an European pattern company. You have to trace the pattern onto paper before you cut it out. I just use regular printer paper and it turns out fine (alot better than commercial tissue pattern paper!!) It's fairly easy to put together, just a bit of piceing to get the patchwork look. Some of the Farbenmix patterns even have sew-along tutorials. Here's a pic of a Vida I just made a few weeks ago.
Farbenmix patterns usually run $10-$14. I got my Vida pattern on etsy for $9.
