This is the “Hearts and Hands” baby quilt from More Quilts for Baby, by Ursula Reikes.
First, you cut strips of fabric.
You have to pick the order you’ll do the strips of fabric, and then you sew the strips together until you have all five strips sewn together. You’ll have several sets of the connected five strips.
Once the strips are connected, you cut them into sections and join the sections in rows, rotating every other section, so that you have a section with stripes going vertically, then a section with horizontal stripes, etc.
Below is a photo of trimming the edges of a row of connected sections, so that the edges are straight.
Once you’ve completed all of your rows, sew the rows together. This will give you the rail fence design. In the photo below, you can see, going across a row, horizontal, then vertical, then horizontal (etc.) sections.
Sew border fabric to opposite sides (top/bottom and right/left).
Here is the completed baby quilt top! It’s actually quite gigantic and more suited to a toddler bed.
