A card for CAS on Sunday

This week at CAS on Sunday it is challenge #7, a sketch challenge  - here is the inspiration

I'm not very good with sketches, I tend to either follow them over-slavishly or drift so far away you can't see the inspiration, but this fun paper that came free with a craft mag several years ago (Yes, I'm still on a campaign to use up my stash) did rather lend itself to the slavish interpretation I feel at home with!
