Tropical

I don't know about Aurifil thread because I have never used anything but Coats and Clarks. It works fine for me. I do agree with Tartan about not obsessing about it. I have only used one pattern and that was for my first quilt top. It didn't come out exactly right because my cutting was a bit off. I often don't use a scant 1/4 inch. I do use the same presser foot for the entire quilt top though. The one that came with my machine is slightly over 1/4 inch. The only time I really worry about seams not matching is when I make pinwheels. All other times my seams come out right. I used to stress about everything and didn't have much fun so I decided no more stressing. It takes up too much emotional energy which I really need for other things. So try not to worry too much, give yourself time to learn and get better at this wonderful craft and have fun.
