What is the golden rule I have broken you ask ?. The measure twice and cut once rule !!
Do you think I can stretch my border to fit ?? I have cut it 139cm instead of 170.5cms No idea how I got it all so muddled. Off to cut another set ( yes, I cut both side borders at the same time!) . Wondering now if I can use the side borders as the top & bottom borders. I'll let you know how I get on.
Hope you have a wonderful day where ever you are :)
