A flock of blue (and pink) birds scattering from the middle of the design, but look at the design the white shapes create.
In the second design the birds are white, apart from a few grey ones who have joined the flock, and the whole design changes.
I have added these templates to my shopping list … not sure if they will work with my method of cutting, but will be well worth a look. (They are top of that shopping list, with things like milk and fruit way down.) I do know I would use a smaller square for the L shaped piece to get the effect I like.
