I found it useful to chain-piece the diagonal rows. First into pairs, then into foursome, then eight...
The dog ears works as a guide when you place your triangles together. No need to pin until you sew the rows together. ; )
Picture shows sections of 4 triangles being chain pieced into a diagonal row.
Before I sew two rows together I finger-press the seams open and give the row a little steam press with the iron.
When sewing the rows together I choose to pin at intersections seam and between them. The dog ears are helpful in lining it all up.
Picture shows how I sew the top together in sections. Three rows in the middle are not pieced together yet.

A few patches are turned backside up on purpose. This gives you a "bleached out" variation of a light print.
So, that's it! I hope you have a good idea of how to make your own Wanna tri? quilt, someday...
Wish you all a great week!
