Experimenting with Cording Foot

this is a faux linen fabric with 2 strands of confetti coloured yarn and a maroon top stitching. I have found some beige poly knit from the 1960's, so i was thinking about making a top and creating some sort of embellishment just to lift the colour a bit...next thing i might try is a loopy beige fuzzy yarn held in place with zig zag and a gold thread mixed in.
