  • To finish you will do some single crochet trimming and surface slip stitching.
  • On the Back Panel where you started with a Fsc you may have some gaps created by switching to csc and joining to begin the straps. Using the Surface Sl St described above in the “Stitch Descriptions and Abbreviations”, work in those spaces to fill in the gaps. This will create a beautiful detail as well as add some strength to the join.
  • Use this same technique in the ExFsc used on the back panel section, again for not just a beautiful detail but to add some more structure to your vest. 
  • Again, using the same Surface Sl St technique, do one row in the final row of csc of the body (Row 3) to create a clean separation of the single crochet and half double crochet. 
  • With your right sides facing, place one round of single crochet evenly around the arm openings of your vest. Be sure to single crochet evenly and periodically check for any puckering. 
  • Once finished, weave in all of your ends and give this vest a good steaming to loosen up the csc. This will help you to have a really good drape and make the vest fit properly, enjoy!
