This is my third sampler from page 92. Mrs Lantz refers firstly to the group: Mosaics. Then the stitch: a flat stitch. She states the source design is 13th century mosaic pavement from the Baptistry at Florence. The design is also found in Franco-Flemish embroidery, again taking inspiration from pavement design.
It’s been difficult to source internet images of the marble mosaic pavement floor at the Baptistry. I have some old photographs of the floor taken in 1988 by my then partner, Mark, but they are not in a media that can easily be uploaded. Lynne Rutter, on her website, Ornamentalist.net, has some very good photographs of the marble mosaic pavement that are crystal clear, though light levels would probably have been very low when taken. I have asked for permission to share these on my blog. I hope to take my own photographs when I visit Florence in December 2018.
Mrs Lantz also indicates that the stitch sampler template below is in use today by American quilters – the Flying Geese. (You can see a nice example of a Flying Geese quilt in The Book of Little Quilts by Katherine Guerrier, page 8. (Purchased Barter Books, Alnwick, in 2015)
Though the sampler is not perfect, my French Knots are a bit irregular, it will hopefully provide a reasonable idea of what the completed stitch looks like.
