I desperately need someones help and I KNOW someone out there can help me. this is my dilemma: I recently started sewing for two interior designers. i got an order for a window seat(which I have never done before) and the designer gave me cord with a lip instead of me having to make welting. the problen is this cording is HUGE. Its about 3/8-1/2″. So with the help of my mom-in-law who has done seat cushions before we made a beautiful window seat with one glich the stupid cording. the cording is acutually 3 smaller cords covered with embroidery thread and twisted together. I cannot sew this with my machine. We have met the two ends at the corner but I cannot connect them or sew the corner shut. This cording also ravels, the embriodery thread that encases the three seperate cords ravels!!! the only thought I have come up with is to some how meet the two raw ends and glue them with something and whip stitch over the raw end to cover it. PLEASE HELP!!! Any suggestions out there??? I am at a stand still and a redo is out of the question. i have already put in 12 or more hours on this! the designer picked out this cording b/c it was the only thing she could find to match.
