-===Speed Piecing Basics===-
-------------------------------------------------------------------------------
Speed piecing is a technique in which larger pieces of fabric are first sewn
together then cut to the size required for quilt block. By using this
technique, and *rotary cutting*, the quilter can piece blocks more quickly and
with greater accuracy.
-==Speed Piecing Squares and Rectangles==-
The easiest speed piecing involves involves piecing blocks or block sections
composed of squares or rectangles. The general procedure is to calculate the
finished width of a square and add 1/2" for seam allowances. Strips of fabric
of this width are cut and are sewn together using a 1/4" seam allowance and
the seam is pressed to one side. The edge of this pieced strip is squared,
then the strip is cut into pieces that are the same width as the original
strips. These pieces are now rearranged as indicated by the block pattern and
are sewn together using a 1/4" seam allowance.
-=Four Square Speed Piecing Example=-
This example demonstrates the piecing of a 4", finished size, four square
block section.
1. Calculate the width of the strips to cut. 2" finished square size + 1/2"
seam allowance = 2 1/2" cut strip. Cut one strip of this width from each of
the fabrics.
2. Sew these two strips together using a 1/4" seam allowance and press the
seam allowance to one side. The strips should be 4 1/2" wide.
3. Square the end of the sewn strip being sure to remove the selvedge from
the fabrics. Now, cut the strip into pieces 2 1/2" by 4 1/2".
4. Take two of the cut pieces and turn one of the pieces over so the
different fabrics are opposite each other. Sew the pieces together using a
1/4" seam allowance and press the seam to one side. The finished block should
measure 4 1/2".
To create blocks or block sections containing rectangles, calculate the
finished length of the rectangle plus 1/2" for seam allowances and cut the
pieced strip into pieces of the measurement. More than one strip can be joined
initially to create other block patterns such as Nine Patch. The quilter
should analyze the block pattern being pieced to see if the technique is
appropriate and, if so, how to implement it.
-------------------------------------------------------------------------------
-==Speed Piecing Right Triangles==-
Right triangles, also alled half triangles, are composed of a square cut in
half on the diagonal. Many quilt block patterns call for two right triangles
to be joined together to form a square.
-=Steps for Right Triangle Piecing=-
1. First calculate the finished size of the pieced square. To the
measurement, add 7/8" for seam allowances. For example, 4" finished sized +
7/8" = 4 7/8" width of strip to cut.
2. Cut one fabric strip this width from each fabrics.
3. Square one end of each fabric strip being sure to remove the fabric
selvedge. Now, on the back of the lighter fabric strip, draw a line the same
distance as the width of the strip from the squared strip end. In the example
this would be 4 7/8". This should create a perfect square. Continue drawing
lines the distance apart down the the fabric strip until the required number
of squares has been drawn. _Note:_ Each square will result in TWO pieced
squares so if the pattern calls for four right triangles in each color to be
pieced together, the quilter must draw two squares on the fabric strip.
4. Next, draw a line dividing each square in half on the diagonal. Draw the
dividing line so that they are in opposite directions on each square.
5. Carefully place the lighter colored strip on top of the darker colored
strip with the right sides of the fabic together and the edges in alignment.
Sew 1/4" away from each of the diagonal lines.
6. Cut the strip apart on each of the marked lines. In the example, this
will result in four squares composed of two right triangles measuring 4 1/2".
Press the seam allowance to one side.
-------------------------------------------------------------------------------
-==Speed Piecing Quarter Triangles==-
Another common piece used in quilt block construction is the quarter
triangle. A quarter triangle is formed by a square cut in half twice on the
diagonal. Many blocks use quarter triangles joined together to form right
triangles in their construction. The steps to speed piece quarter triangles is
very similar to those of speed piecing right triangles with the following
exceptions:
+ The initial strips must be cut the finished square size plus 1 1/4" for
seam allowances instead of 7/8". For a square composed of quarter triangles to
have a finished size of 4", the initial strips must be cut 4" finished size +
1 1/4" seam allowances = 5 1/4" wide.
+ After cutting the sewn strips apart on the marked lines, each unit must be
cut in half again from the corner, to the middle of the longest side.
+ Each marked square will result in four pieced quarter triangle units.
There are many different way to speed piece quilt blocks than those described
here. The quilter interested in speed piecing techniques should check one of
the many *books *on this technique currently available.
