Firstly cut 13/4″ strips from the fabric you would like to sash the blocks with. I have chosen a chocolate brown.
Then trim the block back to 121/2″. By sewing on sashing strips that are slightly larger than we needed gives us the opportunity to make sure all the blocks are the same size.
Then using some of the left over 11/2″ strips that we used in the log cabin and by cutting them into 11/2″ squares we can make a nice feature for the sashing. Place the square right side together with the block, on the corner and sew diagonally through the middle.
