Quiltsmart 101: Watercolor grids

In the early 1990s, Bonny Tinling was making a watercolor quilt using delicate fabrics that had a tendency to shift and stretch ... she needed to stabilize them so her squares would remain square.  She began experimenting with fusible interfacing as a foundation.  She eventually hit upon the idea of drawing a grid on fusible interfacing, placing the interfacing on her design wall fusible side out, then designing with fabric squares aligned on the grid. By ironing the piece, the squares were fused in place.  Instead of taking her squares two-by-two to the ironing board, hundreds of pieces could be stitched as a single unit.  And to top it off, Bonny figured out how to make perfect butted seams that are as thin as possible with a perfect match at every intersection.  Here's how:

Quiltsmart's gridded interfacing is available in several sizes:  1", 1-1/2", 2", 2" On Point, and 2-1/2".
