Eight Patch quilt blocks are designed on an 8 x 8 grid, hence the name. Although this grid is the basis of the designs, often larger pieces are used. The math in an eight patch is usually quite easy, as often quilt blocks are made in sizes 8", 12" or 16" measurements.
Eight patch blocks are usually chosen by experienced quilters due to the number of pieces in the block (but don't let that deter you). Sewing a precise quarter inch seam allowance is necessary in order to match one patch to the next patch. More seams means more chance of error, and these small errors add up. But ... I hope this last note does not deter you from trying out some of these amazing quilt blocks.

The West Virginia quilt block is an eight patch, but, as per my usual method, the pattern instructions will have you construct it as an uneven nine patch, which is an easier method (at least in my opinion).
The block has lots of pieces, but none are difficult -- there are just many seam allowances to be sewn. Half square triangles are plentiful and also a few square in a square patches thrown in for good measure.
The two sample quilts illustrated use standard settings of the blocks -- one on point which the other has blocks set side by side.
