I love the idea of Pinmoors but could not put my hand in my pocket to buy them as they are expensive, they are little bits of silicone you stick in the of your pins when you are quilting to keep your layers together. Usually I use curved safety pins but this pinmoor bungs seem to be much easier.
Someone on line somewhere that I can't find to credit (sorry lovely lady) suggested a product called Everbuild Foam Sealant Joint Backer, which comes in a long length and I am currently cutting off various experimental lengths to see what suits the pins best. It isn't silicone clearly (I think small rubber erasures were also suggested) it's foam clearly but it seems to do the job so far. I am going to pin the edges of my quilt and see how it goes and will give you an update on the sucess of it. The cost £3.24 off ebay so thought it was worth a try, compared to a bag of 50 for £21.95 (plus P&P if applicable from Creative Grids. The roll I got was 10 metres so even if they don't last that long I have plenty to replae them with. As I say I am working out an optimum length for me and test driving them.
I was saddened to hear that Di Huck had passed away recently - she was an inspiration in the quilting world and will be sadly missed - Rest In Peace Di.
So hopefully not too much longer until I can show the finished quilt, there is a fair bit left to do but the majority is done.
