I have had the last supper embroidery design for some time now and finally got the inspiration to do it after seeing the one posted in projects. I am embroidering it on muslin and will put all the blocks together once they are finished. I want to stretch the final product over canvas and then take it for framing. Now my question is..when I seam all the pieces together which would be the best way to do this and how small can the seams be. I am not a quilter in any sense of the word ...so I need a starting point on this one. Since I will be stretching it I do not want bumps appearing from the seams on the finished product..Any suggestions?
