Making one log cabin block
Cut one-inch strips of fabric 22 inches long from both the print and solid fabrics.
Cut two one-inch squares from one of the solid fabrics.
Sew the two solid squares together (# 1S and # 2S), right sides together, using a 1/4" seam.
Finger press (or lightly press with a dry iron) the seam allowance to one side.
A note on pressing: if you decide to finger press at the outset, then continue to finger press all the way through. In this manner, your blocks will be closer in size when you are finished.
Sew this piece to a one-inch wide strip of solid fabric (piece 3S), right sides together, with a 1/4" seam allowance and finger press or iron to one side.
Cut the newly sewn piece from the rest of the strip of fabric.
Now you will sew this to a one-inch piece of print fabric (piece 1P), right sides together, with a 1/4' seam allowance and finger press to one side. Follow the diagram for continued placement of the colors.
You will be alternating fabrics as you add logs to each side. Strip piece the rest of the log.
Constructing all the blocks
This doesn't count the block you have already made.
Cut 20 one-inch squares from each fat quarter of coordinating solid for a total of 80 squares. You will have 20 squares of each solid color.
Strip piecing is a technique to enable you to quickly sew lots of the same items together. You sew one item, and then you put the new item right next to the presser foot and allow the feed dogs to grab the fabric and continue sewing - no cutting threads, no stopping and starting, no wasting thread!
Choose one of the solid colors to make the first set of ten blocks. Using a strip-piecing technique, sew one square (1S) to another square (2S) of the same color, matching right sides together, using a 1/4" seam allowance. You will finish with a total of 10 new pieces. Cut sets apart. This is the beginning of the 40 blocks you will need to construct this table runner.
Finger press (or dry iron) each seam allowance to one side. This opens the squares up.
Take a one-inch wide strip of the same color (3S) and place the small sewn piece on top, right sides together. The existing seam allowance should be perpendicular to the new seam allowance. Sew a 1/4" seam allowance. Add another small sewn piece under the first on the strip of fabric but do not overlap them. Sew a 1/4" seam allowance.
Continue to do this until you have 10 completed sets of one color.
Cut the sets apart carefully and finger press or iron the new seam allowance to one side.
Using a one-inch wide strip of print fabric (1P), sew the next log into place. Strip-piece all ten blocks at once, then cut apart and press.
Follow the log placement from Diagram 1 to continue making the first set of 10 blocks.
Repeat the process with another solid color and the print fabric for another 10 blocks.
Repeat the process two more times with the other two solid fabrics. When you are finished with the blocks, you should have 10 blocks with each solid color of fabric.
