Thanks paul that is the calc i used but i went with 850 down but only 10% but if i fill as suggested to 30% it comes in at 1.219oz per baffle does this sound right to you guys?, i also showed my best stitches i had a section on the hem i run off the baffle stitching went real straight i just had trouble holding the hem straight as i went for a small hem and it kept going half off the foot if i wasn't carefull. my top quilt will be spot on as i got the hanf of holding the material towards the last hem, its all a learning curve atb wayne
