I am putting this quilt together. It is one of those jelly roll quilts, but scrappy. Each piece used, has flowers that I love, but some are kind of folksy and others are really nice like paintings of the flowers. So anyway this quilt top has a lot of light colors. I am putting on a dark green border and a dark green back. So what color do I use to machine quilt it? I guess the dark green, but does it work to use dark green bobbin and white top thread?

Sure why not ? I have used different colored thread top and bottom :lol:

Or why not go with a medium green for both?

I always use thread to match the top and backing, but I think as I get better at FMQ and such that I will not always match the fabric and thread. Something tells me that will be a while yet. lol

I'm finding that I like the variegated threads more and more. I only use them on the top, not the backing.

Wow, lots of good responses even in the middle of the night! Thanks I am going to try the two color thing. Dark green on back and white on top.
Thank you each that answered!

My personal preference is to use the color of thread to match the backing in the bobbin and a invisible thread on the top.

I agree with Krazy Girl, variegated thread can really make the quilt colors pop. Nothing like being able to display all the shades of greens.

Tension will need to be adjusted carefully or dark thread will show on top. Even then you will probably still see some of dark on top or white on back. This will show at needle holes and there is nothing you can do about that.

I have used different colors in the bobbin and on the top. Works fine for me.
