I've had an enquiry about the block in the Crisscross quilt. It is simple friendship star block but the effects are achieved through the use of value placement of dark, medium and light fabrics. I assembled loads of scraps for this and used a friend's accuquilt die to cut the 3" finished half square triangles.
Here is a single block
Here is a a diagram of value placement.
|Note the arrows indicating pressing direction|
Alternate blocks are turned to create the overall sense of interlocking light and medium trellises.
I divided my my fabric into two dark piles each with different fabrics, likewise for the light and medium values. This was so I didn't get the same fabric meeting when the blocks met.
I also pressed the seams on opposite sides of the blocks the same way but differently to the other pair so that seams locked when the alternate block was turned.
I started my quilt in a workshop with Jan Hassard who gave lots of information about fabric values and choice and arrangement of fabric. Pictures from the workshop here were posted with permission.
Jan's talks and workshops are second to none.
