The Martha Edlin sampler is now available as a kit from The Essamplaire. I adore this sampler. I have had it on my 'someday' list for ages! The price is a bit steep at $355.00-$368.00 (depending on the fabric count you choose) but this is a large very complex sampler, so the price is not outrageous. It is stitched with filament silk, which I have never used before, but i`m thinking that would be the least of the challenges with this sampler. It looks like a challenging stitch. For a better view, look on page 37 of Samplers From The Victoria And Albert Museum by Claire Brown and Jennifer Wearden, or here on the V&A website.
Keep stitching ladies!
