The fourth facet is complete. Tonight I remembered I should be using a dry iron for pressing the pieces. I can’t believe I forgot to do this! The steam has warped some of the pieces - or maybe it’s my wonky sewing 😬
Regardless, not all the pieces reach the edge of the foundation piece. Can you see all the white bits on the sides?

I intend to hand-stitch the facets together as this is a lot easier for me when working with tricky angles. But I couldn’t resist testing these two facets out together. It’s working!!
