I am Regina from Germany.
For an anniversary I asked for "some" triangle blocks in white and blue.
As I am a paper piecer from the bottom of my heart they where all done using a pp pattern I made - yielding 12 triangle blocks in one go.
After sorting and cutting them into exactly 2 1/2" squares my basket was well filled.
Now I needed help from the spirits that I called! Making baskets from as many triangle blocks as possible could be useful.
I am just digging into the theme.
In this arrangement a secondary pattern appears.
