Perfect timing. Thank you for asking that question and thanks to Margo & ritzy for the answers...I think I will use Sew Fine or Masterpiece to sew the masts down...not so much bulk when turning the seam over. I will be starting Ladies of the Sea as soon as I get done with this year's BOM from Erin Russek(TQS name geoquilter). I have had the Ladies of the Sea kit for a year, I made myself not touch it before I finished the latest quilt...I'm easily distracted by pretty fabric!
Wow, now I'm inspired love your blocks, thanks for sharing!!!
