burdock, top completed

Burdock
90 by 80 inches
90 blocks set 9 down and 10 across
Block finishes 8 by 10 inches

My block piecing directions are here.
*NOTE, I kept all blocks oriented with the burs section pressed south throughout my layout.
This is not required, but helps it all lay flatter.

Assembly 
Set aside 10 blocks.

Remaining 80 blocks
Press half with to the burs, half to the sides.
*Note, the pressed in blocks do not like to be pressed in. I do this mainly to nest, and allow the centers of the blocks to twist back to their prefered status. Twisted sisters seams I call them!
Pair and piece vertically into twos then four vertical block units. alternating the pressings so they are pressed in then out.
Set aside 10 of the units.

Take ten 4-block units and pair into five 8-block units, pressing the left one up and the right one down, and sew. Lay out these 5 units for the top portion of the quilt.

Take remaining 10 units and the 10 set aside blocks. Press those single blocks towards the burs and sew one onto the bottom of each unit.

There are now ten 5-block units
Pair these to make five 10-block units, again pressing the left of the pair up and the right one down.
Lay these five 10-block units out to be the bottom portion of the quilt.

Sew the units into rows, press top row to the right and bottom row to the left and sew the two rows together.
Everything will nest.

My design, use at your pleasure.
