Flat Front Cozumel Shirt Pattern Hack

Hello all you One Thimble fans, I am super excited to be here today with you all.  I’m Suzanne of Winter Wear Designs, and I’ve got a fun and easy hack for the Cozumel that will make it even more versatile in your kiddo’s wardrobes.

This wasn’t the hack that I originally thought I was going to write for you all today, but after a few comments from fellow seamstresses about sons who weren’t huge pintuck fans, or having fears of tackling pintucks, or having fabrics that got lost or distorted in the pintucks; I knew that this was the perfect first tutorial for the Cozumel.  Today I am going to show you how to get rid of the pin ticks and make a flat front Cozumel.  I’ll show you how to make two back options as well, one with a center pleat and one flat back.  And the options just keep coming!!!!


All righty, here’s what you need for this hack:


  • The Front Pattern Piece
  • The Back Shirt Pattern Piece
  • Marking Tool
  • Ruler/Straight Edge
  • Take your Front pattern piece and make a mark at the first pleat marking (closest to the neck opening).
  • Measure from that point 1.5 inches across the shoulder and make another mark.
  • Repeat at the bottom of the shirt.
  • Connect the lines top and bottom.
  • Fold the pattern together so that the lines meet up, pleating out the excess pattern.
  • Use a piece of tape to hold the pattern together.( you can take the tape off later to cut a pintuck version).
  • Take your back pattern piece, measure 1 inch in from center for the pleated back, or 2  inches in from center for the flat back option.


  • Draw a line straight down and line the fold of your fabric up on that line to cut the back.
  • Cut the remainder of your pieces and assemble according to the instructions skipping the pintuck section.
  • *for the back pleat: fold wrong sides together and sew one inch in from the fold 1 inch down.  Press the center of the fold toward the seam to make a box pleat and baste in place.


That’s it – now you’ve got a flat front Cozumel to mix in with your pintuck ones.  What I love about this hack is that is allowed me to use this great print from Hawthorne Threads that would have gotten lost a bit in the pintucks – WOHOOO!

My Boy heads off to his first day of Kindergarten on Tuesday, he’s sweet and silly, and I know he will fly into this next adventure.  So keep sewing for those boys where and when you can!
