This unique quilt has been taught for many years exclusively by Eunice Scully, Quilter Extradinaire, from Ohio.  Betsy became familiar with the quilt at the QU (Quilt University) of the Greater Ann Arbor Quilt Guild several years ago. Eunice originally saw this Japanese quilt but was unable to find a pattern in English so she worked to create her own version and wrote the pattern.  She has taught this quilt class in Michigan, Ohio, and Florida for many years.  She was in the process of retiring from teaching and graciously gave Betsy permission to teach this class and use her instructions.

Betsy has reworked Eunice’s instructions adding more explanations and tools.  This is not a quick quilt, but rather an exercise in color choice, placement, precision cutting, piecing and especially organization.   The result is unique and beautiful.  It will take on your personality with your choice of color and placement.  It can be any size you choose by adjusting the number of blocks you plan and create. Betsy has enjoyed making this quilt three times now.  Challenging and fun from beginning to end. 

These instructions produce a wall hanging quilt 42” x 42”.  Larger if you add borders.

Supply List

  • Sewing machine (power cord, Foot Pedal and any other items you need to sew
  • Neutral color thread
  • ¼ inch machine foot
  • Extra needles
  • 6 inch square ruler (optional)
  • Iron and ironing mat. Or Pressing tool
  • Rotary Cutter and mat large enough to take you 22” WOF strips
  • Scissors
  • Seam ripper
  • Shoe box
  • 32 (or more) business letter size mailing envelopes
  • Pencil with a good eraser
  • 32 or more large paper clips


This pattern creates 32 clamshells.  Each clamshell takes (2) WOF 2 ½ inch strips. So, if every clam shell will be a different color, you need 32 sets of (2) 2 ½ inch strips of each color (64 strips in all). 

If you want each color repeated once, then you need 16 sets of (4) 2 ½ inch strips of each color and so on. 

Precut 2 ½ inch strips packs (jelly rolls) are a good place to start. Make sure you will end up with 2 of each color. For instance, Bali Pops only has one strip of 40 different colors. So, if you use a Bali Pop Roll, you will need to purchase 2 packs of the same color assortment. In any case you will want strong contrast between fabrics so as not to lose the shape of the clamshell as it sits next to its neighbor.  Concentrate on lights and darks.
