This is the top knotted buttonhole stitch, it’s nice the read the description in Dutch.
And the pages with the slipped detached chain stitch. The old Dutch book only has the drawings of the stitch, the new English book has some nice photo’s too.
For my Dutch readers: the description of the slipped detached chain stitch aka losse kettingsteek met een doorgehaald steekje.
This book looks like it’s never been used, it’s only missing the separate cover.
This treasure made my day!
