I love your quilt. And I love to hand quilt. Have quilted about 100 quilts. My criteria for quilting small even stitches is thin batting, thin between needles, and good thread, I love Aurefil brand. If I quilt in a frame, I use a rocking stitch a needle below and a needle above. If lap quilting, I usually stab stitch with only one needle. Using basting spray to sandwich quilt is so easy and saves time. I read to load needle with as many stitches as comfortable and pull through and at encountering seams that are difficult stitch one stitch at a time vertically through the seam and this sh result in nice small stitching. However you do it, find your comfort level and stitch merrily on.
