Rail Fence Quilt Block Tutorial

The Rail Fence Quilt Block is a great block for beginner piecers and quilters. Here is a tutorial on how to make one with just two rails. The rails I demonstrate with are 2″ x 3-1/2″ but that is not a hard and fast rule. Use the size that you need for your project.

If you are new to piecing, one of the most important things you need to do is to figure out how to cut along the straight of grain.  Cutting along the straight of grain means that you are cutting parallel to the selvage (sometimes spelled selvage.)  It is the most stable of all cuts because there is very little give to it. Many quilt pattern designers will specify that you cut the outer border along the selvage because the final quilt will lay flatter and hang straighter.

Crossgrain cuts that are made from selvage to selvage are also considered straight of grain but they have a little more give to them. A cross-grain border is a more economical use of fabric, especially in a very long quilt. You will have seams in a long border, and you do have to pin carefully so that the border doesn’t stretch, but it’s really not a big deal.

Bias cuts are made on a 45-degree angle. Piecing with bias cuts can be tricky. Spray starch and sharp pins will become your best friends if you use a lot of bias cuts.

This is an illustration of crosswise, lengthwise and bias grain in fabric.

If you don’t see the selvage on a piece of fabric, you can always rip it one or two inches away from the edge. It will always rip along the straight of grain. Press that messy edge and begin cutting another inch or sew away from that edge to avoid damaged threads.

A Quick Note:

This is the first project I have attempted to make in our “winter home” – a fifth-wheel travel trailer. That’s the kind with a piece that fits over the back of a pickup truck. In our trailer, that is our bedroom.  So I am working in a fairly small space.  If you do the same, I would be interested in any space-management tips you can offer.

Pressing Quilt Fabric

This is my kitchen island.  I am using June Tailor Cut-n-Press, which has a cutting surface on one side and an ironing surface on the other. I packed my Oliso Mini-Project iron when I left home, thinking it would be a good thing for me on the road. It is, but it gets HOT. Fortunately, it has a “solemate” with it, which is where you can leave it when you are not pressing something.

Cutting:

Measuring Fabric Strips

My CGR12 square ruler was perfect for cutting the strips, but I needed my long ruler to cut them to length. The CGR812 has a nice feature: it counts from both ends. So I was able to cut my strips to length quite easily.

In case you were wondering, here is how I store my rulers when we are in place. (I pack them when we move.)  I hang them from a curtain rod positioned below the window. It needs to mount firmly because those rulers are heavy. That rod is screwed into the side covers of the window.

I have a walking foot on this machine so I have to kinda guess at the 1/4″ seam allowance when sewing two strips together.

Quilt Tip: How to set a seam

Here’s a Tip: Setting the seam on a strip set helps it lay flatter. To set the seam, just press it while the two strips are still together.  Then open it up and press to the dark.  Your seam will be sharper.

It always helps to have a square quilt ruler the size that you need when cutting square quilt blocks. I didn’t, much to my dismay. Later on, I realized I did have a square-up ruler of this size, but I didn’t think of it at the time.  For the record, I do recommend the Riley Blake Designs  Trim-It Square Ruler Pack, which has (5) square rulers:  2.5″, 3.5″, 4.5″, 5.5″, 6.5″.  I will show you one in the squaring up part of this tutorial.

Cutting the Quilt Blocks

Yes, I always pin my quilt units together to make sure the seams just touch each other in the middle. It helps the block to lie flat.  I am a big fan of Clover 232 Pins.  They are thin but not TOO thin, sturdy but not TOO fat.

Pinning the Quilt Units Together

Always double-check to make sure you are sewing your quilt units together properly! Ask me how I know…

Here is what the block is supposed to look like:

And here is the block I made, being introduced to Jack. (the ripper) This is what happens when you don’t pay attention to how you are sewing a block. Fortunately, a Surgical Seam Ripper can make frog stitching (rip-it, rip-it) quick and easy.

Bad Quilt Block Time to square up the blocks

Here is the 6-1/2″ Riley Blake Designs  Trim-It Square Ruler.  Just center the ruler on the block, double-checking to make sure the lines on the block match the seams. Cut around the ruler and you have a perfect block!

For this project, though, I actually preferred the Quilt-in-a-Day Fussy Cut Ruler because I could see through it a little better. To use this ruler, you match the center of the block with the center X of the ruler and make sure the four diagonal lines match up with the corners.

Here is the final block, multiplied four times to make a 12-1/2″ block:
