Ah! A question up there with "do you wash your fabric" (::::shudder:::: that question could cause a riot! lolol). I am a long armer, and sometimes, the thread choice is one of my hardest decisions. I have to look at the fabric - some are so busy, you won't see ANY color, solids- you will see EVERY bobble if it contrasts. I need to look at the piecing - are there large open areas where I want to see the texture and maybe a thread color contrast? Do I want the piecing or fabric to shine? then I could shoot for a neutral. (you would be surprised at what can be considered a neutral. I have a spearmint green that I use ALOT> It adds texture and you can see the quilting, but it does not smack you in the forehead) It is a kids quilt? (those are just 'git 'er dones'.) I open my thread drawer and pull out some choices- couple blenders/neutrals, a varigated, some wildly contrasting....see what I DON"T want. Then I can narrow it down to one or maybe one for the middle and another for a border. nd yes, there have been a few times that I started with one thread and before I made one pass, I knew it was the wrong color. It happens... One time I frogged that row and started over. Another time I just finished the quilt...it was not going to get a ribbon, but the recipient LOVED it. And LOVED the thread color! Go figure!
