Here shows a detail of the back. the ends have been trimmed and any ends which are close to the edges of the tapestry have been secured towards the center to keep them out of the way. There was a previous post on finishing with more detail on this process.
First I pin it out to size doing a little straightening where needed with the wrong side up.
Once I am finished steaming I will allow it to rest , cool and dry. I may not unpin it till tomorrow as the camel colored ultra suede I have ordered to back it in has not arrived yet. I will include some pictures of that later.
Many tapestry weavers do not back their tapestries but I prefer to. It is much easier to keep the dust away with a smooth backing that can easily be wiped clean, and it just looks better to me. Ultra suede is expensive but a nice smooth cotton would work well too. The advantages of ultra suede are that it can be neatly cut with a clean edge that does not require turning under, reducing bulk and the nice weighty feel will help the tapestry hang nicely. It also has a nice rich finish, and it is a tapestry after all.
For Riverside I cut one piece of foam core the size of the actual tapestry and covered with the dark blue Ultrasuede and then stitched the tapestry to the board. To pad the surface a bit and make the stitching easier you can place a piece of flannel or fleece between the board and the fabric.
Then I cut a piece which would leave a three border and covered it in the same way and glued the smaller piece on to the larger. I could then add a picture frame but this seems substantial enough that I could add a hanger or wire on the back and call it done.
