Well, this is horrible isn't it?! But I was never going to like "bling" as a theme, and I didn't have blingy materials in a subtle minty green, so here it is.
A sparkly pound sign seemed to fit the design theme. And "mint" is quite apt to go with it... groan.
I applied green (it is though you can't tell) metallic mesh by machine, then couched a thick thread round the edge by hand. Then I tried to sparkle it up with green star sequins and tiny metallic beads. My stash of shiny stuff is meagre, and I'm fine with that.
So, a tacky tick, but it's done and I'm moving on!
