Sometimes I match bobbin to the backing and sometimes not. I only worry about the the front of the quilt. I'm with the others, do whatever pleases you. Your quilt - your choice.

I usually just try to keep the top and bottom colors in the same color family and/or value so I don't get pops of color from the top to the bottom or vice-versa. Usually on thicker puffier batting this is not much of a problem but on thinner batting it is more critical. For instance I just finished a quilt with Superior Threads' Rainbow in the bobbin and a medium blue and medium green on the top with a lighter weight batting with no problems.

Do whatever looks good to YOU. Wanna show off the quilting-? Go for it with a great contrasting thread! Or blend in-?
Lots of options~~
I usually use same thread in top and bobbin. Makes things easier for me. :)

i use similar colour on the backs of machine quilted projects because my machine quilting isn't really great. for handquilting projects i use high contrast colours because i love the look of the stitches.

enjoy your work! do what makes you smile :)

When I first started, I matched the color of thread to the back so my mistakes wouldn't stand out so much. Now that I am more comfortable with my stitching, I don't mind contrasting thread. I do sometimes use different thread in the bobbin, but I do test it out first to see if I am happy with the way it looks. My favorite threads are variegated colors.

I always use the same thread on top and bottom...so sometimes it matches and sometimes it doesn't. I do like the contrast.

I love contrast, so whatever I like I use. I figure it is my party.......lol!

I agree! But I have found that if I use plain backing with contrasting thread my FMQ "boos" show up much more.

I use the same thread in the bobbin and the needle. I'm a little boring that way.

I like the look of the contrast - whatever you prefer will be the 'right' way :) Creativity shouldn't be judged by the 'quilt police' ;)
