Everyone has given great advice. Jennie Penny's layout is stunning, giving a visual for the idea of putting the blocks on point. I also liked Mkotch's idea about hankies; if you have access to any of them, a variety would be nice as the "other" blocks shown by Jennie. Quilterpurpledog had a good idea of using a thing cloth layer under the embroidered blocks. I think that there is a thin white muslin, but I'm not sure that white is a "thing." Once you find something that you like for the "other" blocks, you can play around with a setting that pleases you. Then you can post a picture and ask for specific help in calculating how to cut the triangle settings for the edges. Step-by-step should keep you sane and on track.
