Rainbow Weave Quilt Along Week 2 – Block Sewing Part 1

Be sure to scroll to the end for important quilt along links you may have missed! This week we are sewing our cut pieces into larger units. Then next week, we will assemble the units into blocks. Several people have asked why I cut out all of the individual units rather than using strip piecing and I’m happy to explain why: because it’s much more accurate!

Rainbow Weave blocks in progress

When you sew long skinny strips of fabric and then cut them, you have a much greater chance of stretching your fabric as you sew. So if I know the units are cut to the correct size to begin with, the blocks will turn out the right size, and won’t warp or stretch out of shape. However, I’m happy for you to continue using any method or technique that you are comfortable with and works for you, because after all, you are the boss of your quilt!!

Once you’ve cut out all of the pieces according to the chart in the pattern, it’s time to sew them into larger units. You CAN sew one block at a time if you like, but I find that very tedious and time consuming.

Triple Square Blocks from Rainbow Weave Quilt Pattern

First sew together ALL of the triple square units then press the seams open when you are finished so your blocks will lie nice and flat. In order to prevent the edges of your seams from splitting open I recommend sewing with a shorter stitch length (like 2.0 instead of 2.5) or backstitching at the start and end of each unit.

Chain Piecing Video Clip

Take a look at this short video showing how I chain piece 2 units together at a time. I use a stilleto for accuracy and make sure I’m sewing with an accurate 1/4″ seam. Take care that you don’t veer off at the end of the square while sewing. I also engage the “hover” feature on my machine (a BERNINA 770QE). This automatically raises the foot up slightly when I stop sewing, so it’s much easier to slide the next set of units to be sewn under the machine.

In this next video, I’m using a Triangle Thread Cutter to quickly clip the threads in between each chain pieced unit. Once I’m through, I’ll sew the other square to the other side to complete my triple square units.

For speedy and efficiency, you can also construct all of the longer units that will be sewn on to the left side of each block. this unit consists of 2 small squares and a rectangle. If you make 11 each of the following units, you’ll be in good shape to finish all of the blocks after next week’s post:
