You did a great job on your first try at Triangles. A very cute quilt.
If you are going to stitch in the ditch it won't matter about the contrast in colors. If you don't like a white or neutral thread try a little stitching in a medium grey. Gray has a great effect of just disappearing on most colors.
Show the completed project, please!
peace
EDIT: as for quilting ideas if you have access to any clip art you can search for specific things like wind or rope or anything you want to put thread to, and get some cool ideas that you can transfer into your design
I did that very thing for the spider I quilted on a spiderweb quilt. I get loots of ideas from simple clip art.
