yeah...i don't get worked up about thread for piecing. i usually use guterman because it's easy to find and plentiful. someone posted a blog about the true cost of thread though, and aurifil actually came out to be cheaper in the long run.
i do like to experiment with threads for quilting. i like the king tut threads for some projects, but they are seem pricey and i find them thick. i have also played with the guterman varigated threads and am somewhat underwhelmed. i don't like having to run out thread to match a colour if i make a mistake, and murphy's laws proves you always end up joining a white run to a dark run it seems, so to my eye the mistake is noticable.
for handquilting - i struggled with perle cottons, though some advice here suggested a different needle would have helped and i loved the way the work looked with them. i LOVE yli handquilting thread, yet do not like guterman hand quilting threads AT ALL.
iwill never ever use mettler threads again. ever.
coats and clark seem linty. don't know why that is, really.
but for piecing i have ceased to even worry much about the colours
