Tumbler - How to do the straight stitching?

I have pulled out my tumbler that I basted last year.  Might be I have to unbaste, iron and baste again - but I will try to just go with it.

Front - Accucut template sewn as leader ender project. Basted with pinmoors and curved pins.

Back Tumbler basted

I've been using Pinterest to find tumbler quilts finished the way I like them.  Instead of doing an all over design I would like to echo all the stitching lines.  I'm going to use black and blue thread so the stitching becomes part of the quilt pattern.

I have been leaving comments on blogs asking the folks for help.

I don't know if I start in the middle or the edge.

I don't know if I do all in one direction (the straight seams or the angled ones).

I don't know if I do an X to divide and do one quarter at a time.

I want to do the straight stitching for this quilt but can pick another edge to edge design and finish using a LeahDay design too. I would like this quilt finished so I can give it to our friend in Colorado.

I have been back from Boston since mid-August but only feeling like I have time to get organized to start new projects and finish old ones!

: )

I forgot to keep all the URLs for the tumbler I saw.  So many beautiful choices....

I don't really know how to use Pinterest, but have been collecting some sites there... it's really fun to look for different images...
