After I turned a ladies skirt into a dress for a little girl, I had this lovely off cut complete with invisible zip.
The first step was to cut out the purse shape keeping the zip. The most important part is to make show the slidder doesnt fall off or get cut off!
My first thought was a french seamed little purse, but you couldnt move the zip when it was the right way round! i think thats because invisible zips are a bit funny.
