The pattern is the Phoebe bag, a free pattern which you can find on this blog.
I saw some lovely versions of the bag on Pinterest that had centre panels of contrast fabric and I wanted to do the same. I'm not sure if I went about it the right way as my bag ended up smaller than I think it should have. I'm one of those people who really need a pattern!
Fabric ~ Contrast fabric from Spoonflower and some black linen-like fabric (??) from Spotlight
