Because it is a wall hanging I really like your choice of fabrics. They lend themselves very nicely to the pattern you chose. I think it is fun to utilize the characteristics unique to different fibers. I think your greatest challenge will be quilting the dotted swiss fabric because your needle will bounce off of the dots. Perhaps the quilting in the dotted swiss area needs to be simple but I think you could use quite intricate stitching like feathers in the linen areas. Perhaps stitches need to be larger than usual because the threads in the linen are large and thick. I will certainly look forward to what you choose to do.
