The Card Trick quilt block was designed in the 1970’s by Gutcheon in McCall’s. Beth and Jeffrey Gutcheon were quilt book authors and McCall’s magazine has been publishing all kinds of patterns and books forever.
“Jeff Gutcheon did design the card trick block back in the 70’s. He and Beth (who also wrote The Perfect patchwork Primer, and is now a distinguished and successful fiction writer) were WAY ahead of their time. Their Quilt Design Workbook was by far the most innovative and influential book on contemporary quilting. Things like chain piecing, and new designs such as card trick and many other features were considered great leaps of quilting in a day where all you could find were ditsy calicos.”
