Is that why I have so many different colours of thread in my bin? I've been buying 2000m spools of Mettler cotton in a light taupe and seldom use anything else, except black. I did buy some white thread recently but it wasn't really necessary. If I ever take up hand applique, I have plenty of colour matchy thread to use.
The more I piece, the better my seams become and the less trimming my blocks need. I love it when blocks just sit together nicely. My method has been to make things larger and trim down but I'm doing that less and less. I have been working on my pressing technique and have found that using a clapper and really flattening down the seams is making a huge difference in accuracy.
