Well thanks for all your posts...I tried my red clips...I found them hard to open, but that's because I had thumb surgery back in Aug and still have a while to go for 100% usage..the jury is still out on this one...I tried sewing along side the ends of them...nope that didn't work too good..I have a small Janome machine and it doesn't feed the binding thru really well..I have to have my left hand behind to help pull it thru...I guess with a more expensive machine, I wouldn't have that problem..it does 2 or 3 thicknesses ok..get to several layers and it needs help...I will try them again on my next project...and see ...I don't understand the point of the marks on them...am I missing something..?? How do you use them for the marks to work.?? thanks again..for all your views...
