'Dirty denim' skirt

I've been away quite a lot. I was away with work for 2 days and then went straight to see Yorkshire Lass for the weekend. Came home for a day and then away with work for another three days. Came back yesterday evening and only started to sew again tonight.
Fortunately I am not working this weekend and hope to catch up with housework and sewing.

I am sewing a 'dirty denim' long straight skirt from Simplicity 9825 with the browner side out, the brown and blue together look sort of olive, and this will probably be the final piece in the Botanical Garden SWAP.

The 'dirty denim' I am using here has tan coloured threads in one direction (which would normally be white ) and then very dark indigo in the other. As a result its kind of dark brown one side and sort of olive coloured the other. Here I am using the back which is the greener side.
