So I had a play and I didn't find it quite as fiddly as I thought I would.
I've done my card using the colours asked for by CAS Colours and Sketches -

I'm also adding this one into Watercooler Wednesday's Anything Goes challenge
I used one of the Bold Butterfly framelits from SU and its quite a small little framelit which makes the little pieces even tinier. In case you don't know what this technique is - its basically taking a framelit with lots of pieces in it, pushing out the inlaid pieces which have been coloured and reinserting them in the correct order in a white version of your framelit.
As this was a colour challenge I inked up a piece of Whisper White with Soft Sky and Berry Burst. My Soft Sky ink is very dry and doesn't really give a very true indication of the colour. I went over the pieces once they were inlaid in the white butterfly with a blender pen inked in the two colours just to give a bit more definition. The butterfly was then simply layered onto some Stitched Framelits and the sentiment is from Feather Together inked in Sahara Sand.
Thanks for stopping by - let me know if you do a similar technique and I can come and visit.
