So after careful consideration and upon pondering on it for some time, I decided to go with this simple border. The border is comprised of a row of single crochet, followed by a row of double crochet, with 3 double crochet at each corner. The space in between double crochet stitches is the result of skipping one stitch, doing a double crochet, then returning to the previously skipped stitch and do a double crochet.
Remember that there are four colors to this Afghan, so I decided to use the same color as the knitted panel. This way it will not look weird. I did start to do a different combination and permutations and more combinations and did not like the looks of it, so here it is almost ready for the showcase. Thanks for stopping by.
