Almost all pieces are cut using a pair of scissors.
I started the constructions by cutting a long strip and then I cut them in sections at irregular intervals. Then I cut small rectangles to insert in between the larger strip sections.
I stiched all bits together as per (this very bad) photo.
This is the next major block I constructed in a similar way as the previous section. I stitched two thick and wide blue pieces to a middle red narrow strip. Then I cut across and the resulting pieces were sewn again with another narrow red strip.
The white block was too wide so I trimmed it and used the trimmed piece to make the other piece larger so that both pieces could be stitched together.
I made a few mini log cabin blocks too.
The bigger the piece the more uneven the sides get.
Square the sides.
Quilt any way you like.
