This is a VERY simple block. Foundation pieced. I won't give too much instruction, since we've all done complicated foundation piecing now and this is really easy.
IMPORTANT!!!! You have to make a mirror image of the diagram. The foundation paper is the back of the block, so if you don't mirror the diagram, your block will be a mirror of what you want.
CD users take note: I assumed that if you print a foundation pattern, the software will know to mirror the pattern. It doesn't. When you print, there's an option to mirror the printout. Select this! Also, the software will default to a 4.5"x4.5" block. Again, change the size to 5"x8" before you print.
Trace or print the diagram onto your foundation paper. Number your sections if you want to. It's really a very simple bottom to top construction.
(This is not a scaled drawing of the block. I just drew it to show the numbering.)
Using your preferred foundation piecing method, construct the block, following the numbering.
When you have completed the main section of the block, you will probably have something resembling this.
At this trim the outside edges to ¼", before attaching the outside strips.
Complete the block. Trim, remembering to add ¼" seam allowance all the way around. Remove the foundation paper.
