I have quilted for almost 20 years and close enough was good enough especially when you are doing the same block over and over. I an now working on "The Orphan Train" with 6 " blocks. Last night I spent quite a bit of time getting that 1/4" seam. I finally got it on my main machine. In order to get it I have to lay the ruler cutting line just a tad to the left of the fabric and also use a Scant 1/4. Then I worked on me 301 that I take to classes. I think I have done everything I need to but I have Aurifil thread and will use that. I think that will make all the difference. Thanks everyone for your help.
