working with half square triangles and quarter triangles that SCANT 1/4" seam makes a difference. wouldn't think so but it does. i learned the hard way myself thats why i make one block completely before sewing the others to check the size. i got a ruler from guidelines4quilting.com that has the 1/4" seam allowance in when you use the guide line markers. haven't tried the ruler out. already have my blocks cut out so i guess i will do the scant 1/4"
