Cluny needlepoint

Recently I won 2 tapestry canvases on Ebay for a fraction of their retail price but how to work them so that the fine detail shows has been a problem. I considered all sorts of options but have decided that the best way to do them is to use Paternayan and Elsa Williams yarn. I think the final product will look really good because of the ability to split the Paternayan wool. A difficulty is that both these yarns have been discontinued apparently so getting hold of the yarn is dicey. I have enough of the Elsa Williams to do the burgundy background and I am waiting on a response from a seller who may have the Paternayan. Fingers crossed.
Here are the unworked canvases - they include a lot of fine detail so I reckon they should keep me occupied for some time. I would love to see the original Cluny tapestries.
