It’s hard to read because stitching at this size is not easy but they say: “Deux estions et n’avions qu’ung cuer.” Which is a verse by Francois Villon, a French poet and ne’er-do-well from the 15th Century, and translates roughly as “we were two but with one heart” which for a pair of garters has an entirely different meaning.
The embroidery is chain stitching for the outlines, satin stitches on the leaves and backstitching on the writing. The fabric is silk taffeta, the thread buttonhole silk and the ribbon is silk too. Only the backing (not pictured) to give the main part some additional stability is a ribbon out of cotton.
The background fabric is a my court gown petticoat which I am currently wrestling with. I am not sure it is that difficult because I am afraid of wasting/ruining my fabric or if it’s just the usual “I am nearly finished, so why actually finish” fatigue. (I mean I am one sleeve decoration away from finishing a cotton robe anglaise, so there is that.)
