A Hera marker works great!!

One quilt I just sewed from one corner to the next on the squares but this wont work unless you have small squares.
For same size widths for lines I just use the attachment that came with my walking foot that fits in the hole in the back and is adjustible for whatever width you want. It works great.

I just started quilting with diagonal lines and am using a Frixion pen to draw on the lines. I find the center by folding my quilt at a diagonal matching up the corners and gently pressing with and iron to create a crease, from there I draw the lines in my quilts. I haven't used the bar for my walking foot, not sure how much I trust it.

Here is what I do...[ATTACH=CONFIG]313094[/ATTACH]

I like the bar that fits behind the foot, done many that way and they always have turned out.

I use the blue painter's tape -- I put it in the middle to get the first line straight and then use the width of the presser foot to follow along.

I mark the diagonals with disappearing ink and stitch on that line. Works very well for me.

Are you talking quilting or sewing a top on diagonal

I too use painters tape. I have it in diff widths.

doing the quilting lines straight, any design. could be grids, could be like sun rays, etc. but straight.
