Pattern Notes
The counterpane is knitted first, then the fabric portion is cut to fit the counterpane -- gauge is not important!
All seam allowances are 1/4".
Counterpane
CO 8 sts evenly onto 4 DPN (2 sts per DPN). Join for working in the rnd being careful not to twist.
Begin working Tricornu chart, working 4 reps per rnd. Work entire chart once and then BO knitwise using the decrease BO.
Decrease BO
Knit 2, sl sts back onto left needle, knit them tog tbl, *k1, sl 2 sts onto left needle, knit them tog tbl*
Biscornu Lining / Bottom
Measure counterpane stretching slightly. Cut 2 fabric squares to this measurement plus 1/2" for seam allowances.
Note: We've added a step-by-step tutorial of sewing the biscornu. {view the tutorial}
Make scant 1/4" snips halfway up each edge (see gray lines in below diagram). Place squares right sides together as per diagram and starting at top sew seam matching red stitching on diagram.

Rotate top fabric 90°and and sew second half of seam along the bottom panel. Repeat for other 3 panels, leaving a 1.5" gap in the final panel.
Turn biscornu right side out. Firmly stuff with fiber fill and hand sew gap shut.
Hand sew counterpane to top. Attach buttons to center of both sides of cushion using button thread. To attach buttons tightly, sew through each button once and then pinch buttons together with thumb and middle finger of one hand while pulling thread taut with other hand. Sew through both button a few more times while pinching. Push needle through slowly so you can avoid sticking yourself.
