I found the pattern
here in case anyone else wants to take a look at it. Very pretty.
From reading the pattern, it looks like you should double crochet in the first chain 4 space and then continue on. Check your stitch count at the end of this row. It should match the first row which is
19 (22, 25) ch-4 spaces, 20 (23, 26) dc....since it appears that the piece is crocheted as a rectangle until the upper edging. If you have one extra ch-4 space and one extra dc, then rip out the row and skip that first ch-4 space.
Make sure you post here and let everyone know your discovery! And of course you must share a picture when it's finished!
