you might be better off starting your first lone star following the pattern- once you see how it all comes together you will be better 'equipped' to modify it for a future project. it's one of those patterns that does not necessarily just work if you simply increase the size of the strips. I think my last lone star (54") I used 7 fabrics ,,, or maybe it was 9, now I can not remember- will have to get it out later & look. follow the pattern and work out all the (glitches) learn the pattern- then choose the fabrics you want for your larger one. there are patterns for them in many different sizes- or you could draft it out on graph paper before diving in. to choose how many fabrics, your colors you could copy the picture of the lone star, print it off in gray scale- then color it with colored pencils or markers to see how your colors/choices will work.
