You will need...
Gold leather or faux leather
Stick 'n' Stay craft mount
Sewing machine or stapler
Black laces or ribbon
This turned out to be one of my more challenging and time-consuming projects, taking more than five hours to make, so I'm writing it as a log of what I've been getting up to and what I learnt to do differently.
How to make them
From here onwards is where I would change the method to make the project both easier and neater. What I should have done and would recommend doing would be to cut away the remaining fabric from the boots completely, fold it in half, trace the design onto the other side and cut it out. I would then have needed to cut away the fabric on the other boot, laid it flat, traced the design onto that and cut it out.
My next step would have been to lay the two cut out pieces face-down onto the gold material, facing the 'wrong' side, and trace around them with 2cm strips where I wanted the laces to go (which I'd fold into loops - as I did later on) and 1cm of excess fabric along the base, before cutting them out. After cutting both pieces out, my last steps would be to stick them to each of the matching pieces of material I cut from the boots with craft mount and attach them to the boots by stapling the material along the soles.
