Easy and Simple Free Sailboat Quilt Block Pattern

Hi Everyone!  I am so excited to show you how to make a classic quilt block, the sailboat block.  The sailboat block is easy and fun. 

You can use the sailboat block in an entire quilt, wall hanging, pillow or other projects. It's an easy block to personalize in a number of ways to create a baby quilt, a boy quilt or a nautical-themed nursery.   To make a quilt using this block, check out our sailboat quilt tutorial.

Have fun choosing the fabric for the colorful boats.  This block can be used as a fabric scrap stash buster since the boats and the sails can be any color.

STEP 1: Cutting Fabric

Before cutting the quilt fabric, I suggest you use Mary Ellen's Best Press.  It removes wrinkles and gives the fabric a soft but firm texture which makes cutting and assembling of the block easier. It can be purchases at Amazon and many quilt and sewing shops.

STEP 2: Assembling the Sails

To assemble the sails, you will need two 3 1/2" squares of background and two  3 1/2" squares of sail fabric.  You will be making half square triangles with these squares.  

To make the first half square triangle, with a pencil on the wrong side of the lighter fabric draw a diagonal line from corner to corner.

With right sides together, lay one background fabric and one sail fabric together aligning all raw edges.  At the sewing machine, attach the quarter-inch piecing presser foot.  Then, sew two seams by stitching one-quarter inch away from the drawn diagonal line on each side.

If you don't have a quarter-inch piecing foot, simply draw two more lines, each 1/4" away from the original diagonal line. 

A quarter-inch presser foot is an essential tool for quilters.  Interested in purchasing a quarter-inch presser foot, Amazon has many at reasonable prices just be sure to purchase one that fits your sewing machine.

Repeat with the other two squares.

With a scissor or rotary cutter, cut along the marked center line.  With an iron, first press to set the seam and then press the seam allowance toward the darker fabric. You now have four Half-Square Triangle blocks.  

With a ruler, trim each half square triangle to a 3" square.

Still unsure how to make half square triangles?  We have a half square triangles video tutorial showing this technique.

We have also discovered this Trim-Lock Quilt Block Trimming Tool that makes trimming half square triangle blocks quick and easy!  This tool is used after you've pressed the block open.  Click the link to view the demonstration for this Trim-Lock tool.

You will be piecing the four blocks together, by making a four patch block with the sail pieces.  To do this, before you begin to sew the blocks together, lay the blocks on the table so all the sails are going in the right direction. 

Begin with the top two squares,  place them right sides or pretty sides together matching the raw edges.  Sew along one edge. Repeat with the other two squares.  Press the seam allowance toward the background fabric.

Now take the two rows of two blocks and sew them together.  The four-patch square is finished.

After finishing the four patch block, sew a 3" x 5 1/2" rectangular piece of background fabric to each side.

STEP 3: Boat Assembly

To make the rectangular boat strip, make half square triangle with the final 3 1/2" piece of background square and the 3 1/2" square of boat fabric.  Draw a diagonal line from corner to corner on the lighter fabric.  With the right sides together, lay the pieces together aligning the raw edges.  Stitch one-quarter inch away from the center drawn line on each side.

As previously explained, cut on the drawn line, press the seam allowance toward the darker fabric and trim the half square triangles to a 3" square.

Sew one half-square triangle to each side of the boat hull which is the 3" x 5 1/2" rectangle.  Press the seam allowance toward the boat.

STEP 4: Sewing Block Together

To sew the block together:

Sew the sail section and boat section together.  Then sew the 3" x 10 1/2" background strip to the bottom of the block.  Press the seams to one side. 

The sailboat quilt block is finished.

Happy Sailing!
