In both these samples bonded fabric has been used.  During my tutorial Sian emphasised how successful relating the type of insertion to the fabric's surface pattern could be. 

In the top sample two sizes of sequins have been trimmed into irregular shapes and applied across the seam.

In the second sample irregular holes of differing sizes have been cut into the seam and the shapes turned over and appliqued on to and overlapping the seam.
