In October, I participated in a biscornu swap in one of the groups on Ravelry. My swap partner has already received her biscornu, so I can post pictures here without spoiling her.
Some more information about biscornus, from Biscornu Basics:
A biscornu is an interesting little eight-sided pincushion that has become very popular in recent months. … Regardless, biscornu are basically made from two embroidered squares sewn together on point; the corner of one square meets the middle of the other as the two pieces are whip-stitched together and stuffed, creating the a quirky, skewed pillow. Additionally, many are finished off with a button in the center of the design top and bottom.
I used black Aida, two colors of blue, green, and BEADS. I used the Rhodes Butterfly Biscornu pattern from Kincavel Krosses. I learned a new stitch! I liked making both the Rhodes Butterfly (of which there are many variants) and the Rhodes square.
