A quilt usually consists of three layers, two layers of
fabric with a layer of batting sandwiched between.
To sew three layers together, you have a wide
variety of stitches and techniques to choose from.
Attach the straight stitch needle plate when piecing
your quilt. The smaller hole in the straight stitch
needle plate supports the fabric closer to the
needle and helps prevent the fabric from being
pulled down into the bobbin area, especially at the
beginning and/or end of a seam.
The patchwork program makes it possible for you
to program an exact seam length that can be sewn
repeatedly. This is very useful when quilting,
especially when piecing many quilt blocks of the
same size.
See page 4:12 on how to use the patchwork
program.

When possible, press seam allowances towards the
darker fabric.
Assemble the pieces according to the pattern
instructions. Layer the pieced quilt top with batting
and backing. Pin baste the layers together in
preparation for quilting.
