They look awesome!! You can send me your test blocks ...HAHA One day I'm going to get a package because i keep saying that....I hope!! They look awesome.....How are you pressing the seams? Are you making sure your pressing and not ironing? That can send a tiny difference....One that always happens to me mainly with points is everything sews right and consistant til that last 1/8 of an inch of fabric at the end where the tip is and I notice and yes I have resewed this many of times but some how the last 1/8 of sewing my 1/4 inch seam goes slightly like a triangle...grrr when that happens!! Happy quilting!!!
