As mentioned here, Elizabeth from Oh Fransson designed this "Map of the States" block and she gave me permission to post my 'stack and slash' method of putting it together. So here goes. These instructions will give you 12, 10 1/2 blocks (including seam allowance).
Cut 12, 13" squares and stack them into 2 piles of 6. Iron them on top of each other, so they stay together when cut. Put aside one stack of 6 squares.
I've used Denyse Schmidts Hope Valley range and added a couple of solid fabric squares.
Using your rotary cutter and ruler, cut through the stack of fabric 3 times, so you have 4 strips. Cut on a slight angle - about 1/4 inch difference from top to bottom. You can vary the angle and the width of the strips.
Move the top fabric of the second strip to the bottom of its pile.
Move the top 2 fabrics from the third strip to the bottom of its pile.
Move the top 3 fabrics from the right hand strip to the bottom of its pile.
Sew the top strips together using a 1/4 inch seam. Press seams to one side (or open).
Then sew the next set of top strips together and so on until you have sewn 6 blocks of 4 strips.
Take your other stack of 6 square that you set aside earlier. Repeat the above instructions, except this time make FOUR slightly angled cuts, yeilding 5 strips.
Similarly, sew these together yeilding 6 blocks of 5 strips together.
Then place a 4 strip block on each pile. These blocks will be slightly larger, but don't worry, you can trim them later. Just line the blocks up on three edges.
Now, place another 5 strip block on each pile, but this time ROTATE them 180 degrees. This will add interest to your finished block.
Place another 4 strip block on each pile and ROTATE them 180 degrees.
Place a 5 strip block on each pile (you don't need to rotate these ones).
Place a 4 strip block on each pile (you don't need to rotate these ones either). Your 6 blocks of fabric should be lying directly on top of one another. I folded these over so you could see the layers.
Now, take one of the piles of strip blocks (and put the other aside). Rotate it so the strips are lying horizontally and the top of the blocks line up.
Make 4 slightly wonky cuts to create 5 strips.
Move the top fabric from strip 2 to the bottom of its pile and so on (same method as you used for constructing the strip blocks).
Sew the top strips together to make 6 Map of the States blocks. Trim to 10 1/2 inches.
Repeat procedure with your other stack to yeild 12 blocks.
I've made 12 grey/blue/green blocks and 12 pink/orange/purple blocks. Now I just have to decide what I'm going to do with them. Make 2 baby sized quilts? One large quilt? Sashing, no sashing...?
Alternatively, you could make 10 blocks at a time. Just use 10 squares of fabric and instead of dividing them into piles of 6, divide them into piles of 5.
Thanks again Elizabeth, for your generosity in sharing your designs so freely and inspiring so many of us.
