My 2Nd Attempt With A Roper Wallet

[Avion]

A friend wanted a Roper style wallet, so hare it is. I think I am improving but there are still glitches here and there, hopefully one of these days I'll get one without any! I also have a question about stitching...down by the left hand corner I ran out of thread, so according Al Stohlmans book I tied off, reloaded the needles, and started 3 stitches behind the last stitch to continue, but that makes those stitches more chunky and it really stands out. Am I understanding correctly this procedure? Is there any way to get rid of that chunky look?
