CAS(E) this sketch #122.
I kept it really simple and CAS in my opinion.
I had to use 3 butterflies as 3 just looks better I think.
The green banners are made with Talens ecoline and a very wide brush, right on the cardfront.
The thanks is from Memory box and simply cut out from white cardstock, so it would pop.
I think i regret giving the butterflies some shading, but hey...never mind ;-)
