Thanks so much, I do not ise patterns, I only invent something on my mind, and start to worl on it. This is size 4 toddler, Let me try to explain what I did, hopefully helps you. I chained 43 , first 2 rows 42 half crochet, row 3, chain 3, triple crochet 41 (make total 42 counting the chains to raise up) I did 39 rows for bottom. then finish 2 half crochet, For top back, skip 11 rows and start with 6 chains double crochet towards center of rectangle, chain 3 and repeat to cover the center 17 triple crochets. 2nd horizontal road 34 double crochet, repeat for a total of 6 rows. Row 7, 11 triple crochet, 3 double crochet, 2 half crochet; 2 slip stitch, 2 half crochet, 3 double crochet and 11 triple crochet, repat one more row identical and finish. That will give the neck space without cutting yarn.
