Here are my first set of loomed flip flops using Dana Kruse Pattern. The pattern said knit 10 rows then attach to flip flops. I did that with the first one, but I missed several stitches and had to tie off the missed stitches, doesn't show just has a tighter look to flip flop. On the second flip flop I knitted 9 rows attached knitting to flip flop then knitted off the 10Th row and I also hung stitch counters on the loops I was using to attach to peg like you do for a cuff or hat brim. It made it easier to find the stitch when flip flop was in position to b attached. I use the counters that look like little plastic diaper pens.

Here's the finished hat for my 13 year old granddaughter Marissa.
