This is the archive listing of all Quilt Blocks in the Quilt Block Library assigned to the Patterns Category that are considered BASIC UNITS in quilt blocks

Battleground Quilt Block

Skill Level: Confident Beginner

The Battleground Quilt Block is basically just the half square triangle on steriods! It's a great way to use up leftover half square triangles that are produced when you use the quick corner method to make flying geese, square in a square units or snowballs.

Obviously, it produces a great looking scrappy quilt.

Split Rectangle Quilt Block Units

Another advanced basic unit is the Split Rectangle quilt block unit. Sometimes this unit is called the Half Rectangle Triangle or HRT. You can find examples of this unit in action in the following quilt block designs:

Now, don't be fooled into thinking these units will work just like half square triangle units. They won't. They are an entirely different animal.

For starters, a half square triangle will always have the same height and width. This is not the case with Split Rectangles. They can come in a variety of height to width ratios, as shown below.

Note the variety of widths and heights in these split rectangle quilt block units.

 

One important thing to know when making these units is that the diagonal can either go left to right or right to left. Since the two different directions are mirror images of each other, care must be taken when cutting your fabrics to make sure you haven't reversed the unit.

The formula for making Split Recs is pretty differently from making HST's too. Recall that when making Half square triangles, you will add 7/8" to your finished size, then cut on the diagonal. To make Split Rectangles, first determine the finished size of your rectangle, then add ¼” to the width and ½” to the height.

Here's an example: Suppose I want to make to have a finished Split Rectangle that measures 3"x 6". Then I would need to cut rectangles that are 3.25" x 6.5", then cut them along the diagonal.

A tool that makes easy work of Split Rectangles is the Split Rects Tool by Studio 180 designs. I've found this tool to give me great results and it really speeds up the cutting process when making these units.

Corner Beam Quilt Block Unit

Another basic building block unit in quilting is the Corner Beam unit. This unit is not seen as commonly as others, but the Corner Beam unit is an important design to master once you get the hang of the other basic units.

I have constructed this unit successful using two different methods. One method to make Corner Beams is to use Foundation or Paper Piecing. You can download a simple paper piecing template by using the link below.

The downside to paper piecing is the amount of fabric waste. Another great way to make Corner Beam units is to use the Corner Beam Ruler by Deb Tucker of Studio 180 designs. Her ruler allows you to make quick and accurate corner beams with less waste than paper piecing.

The following blocks are examples of blocks that have the Corner Beam unit in their design:

Candy Stripe Units

What I call a Candy Stripe Unit in quilt block construction is when you have a parallelogram flanked by two right triangles. The resulting unit is a rectangle. You often see parallelograms in blocks that required Y seams.

Below are a few quilt blocks that have parallelograms in their designs:

There are two ways to approach constructing these units.  The first way is to divide the parallelograms into two Half Square Triangles. Many times this will be the best method, as the Candy Stripe Unit method doesn't always lend itself to every design.

Another approach to making Candy Stripe Units is to make them using a Quick Corner method. This technique is similar to how Quick Corner Flying Geese are made, except that the 2nd corner is stitched down parallel to the first corner. The rotary cutting measurements for each piece are identical to how you would cut Flying Geese pieces when using the Quick Corner method. (You can use the cutting chart located on the Flying Geese Basic Units page.)

As shown in the chart, you will need to cut 1 base and 2 small square for each unit that you make. After you cut your pieces, draw a line down the diagonal of your two small squares. Then sew the pieces following the steps below:

Step 1: With right sides together, align the first small square to one side of the rectangular base. Stitch on the diagonal line.

Step 2: Trim

Step 3: Press stitched fabric open.

Step 4: With right sides together, align the second small square to the other side of the rectangular base, making sure that the drawn diagonal line is parallel to the stitched diagonal line of the other small square.
