This embroidery is from Egypt, although the Ashmolean Museum has the dates of construction between 10th to 15th century. It is linen embroidered with dark blue flax, 15.5 long and 13 cm wide. The “trees” have three different ovals, but not enough of the embroidery survives to see if a pattern developed.
I have charted up the pattern, which is available as a pdf-
There is a similar embroidery in the Victoria & Albert Museum–
This is the top embroidery, which is linen embroidered with dark blue silk and a twisted linen fringe. The “trees” have a slightly different design but the same oval designs as the embroidery in the Ashmolean Museum. The medallions are of the same dimensions but a slightly different filling design. The V&A Museum also give the dates of 1250-1516 C.E.
The pattern is available to download as a pdf document-
I have not charted up the bottom pattern darning embroidery, but will be doing it soon. Let me know how the embroidery goes!
