This yardage guide might help, although amounts could vary depending on the size of the finished block. I have the Accuquilt die for Hunter's Star, which makes a 12" block, but I'm not sure how much yardage I will need. I like two colors, but I am thinking I will keep the light parts the same fabric but make the dark parts (probably red) scrappy so I can use up more of my stash fabrics. Anyway, here's the yardage chart I found online:

Oh, I also think that *how* you make the Hunter's Star block will affect yardage requirements. My die cuts large pieces, but some patterns have you construct those pieces from squares and triangles. The latter would require more fabric because of the extra seams.
