I am sure you all will get tired of my questions, but I am just reading over the pattern for the Stars Ablaze quilt I will start cutting out soon......the directions in the book are for a wall hanging, then it gives the number of finished squares and yardage that you need for a full size quilt.....my question is about borders.....the directions say to cut the borders parallel to the salvage edge....but it doesn't give me the exact size for the double size quilts just the wall hanging.....do I just work out the finished size and cut along the salvage edge or do it piece it....I am thinking the borders should be all one strip but I want to make sure....plus no matter how hard I try to cut long strips and keep them exactly the same size all the way down I end up being off just a tad.....any useful tips if tricks for doing this accurately?

thanks!!
