I bet I have stitched a million french knots over my life time! I feel that I am a pro at them. I am not so sure that I am all that innovative with them though. I used them to hold on the sequins in the bottom photo. Truly that was out of the box for me as I usually use beads for that! giggles
The top two pictures I have used silk ribbon to make the french knots. I can't claim that as an original idea as that is a kit I purchased and stitched.
