Click on "Download This Project" to download the full-size foundation patterns. Print out each foundation pattern 25 times on printable foundation-piecing material. (Or trace each pattern 25 times onto lightweight tracing paper, tracing all lines and numbers.) Cut out on outer dashed lines to make foundation papers.
1. For a Body Unit, you’ll need five violet blue print small triangles, an assorted print small triangle, an assorted print 2-1/2x6" rectangle, and an assorted print large triangle (Diagram 1); refer to the Quilt Assembly Diagram for ideas on mixing and matching your assorted prints in the dragonfly blocks.
2. With right sides together, layer a violet blue print small triangle atop the assorted print small triangle, aligning triangles' short edges. Put a Body Unit foundation paper atop violet blue print small triangle, positioning fabric under area 1 and aligned edges 1/4" beyond stitching line between areas 1 and 2 (Diagram 2). To check placement, pin through all layers on stitching line and flip assorted print triangle open. It should completely cover area 2 and extend at least 1/4" on all sides. If it doesn’t, reposition pieces and check again. With foundation paper on top, use a short stitch to sew on first stitching line through all layers.
3. Trim seam allowance to 1/4" and press assorted print piece open (Diagram 3). Trim both triangles to scant 1/4" beyond adjacent stitching lines and even with edges of foundation paper.
4. With right sides together, position another violet blue print small triangle under trimmed assorted print piece with triangle’s short edge 1/4" beyond second stitching line (between areas 2 and 3). Sew on second stitching line (Diagram 4). Trim seam allowances to scant 1/4", press violet blue print piece open, and trim edges to scant 1/4" beyond adjacent stitching lines (Diagram 5).
5. Continue adding pieces in numerical order, trimming and pressing after each addition. Trim all fabric pieces even with foundation paper edges. With blunt edge of seam ripper, remove foundation paper to make a pieced Body Unit. The Body Unit should be 5-1/2" square including seam allowances.
