This is a brief tutorial I wrote up for my fellow members of the Love Circle of Do. Good Stitches to use to make this month’s blocks. I was playing around with this idea in a quilt I made recently, but modified it just a bit for a clearer result. These are the colors I used as inspiration for my blocks:

These instructions are for making two 12.5-inch blocks.


To make these blocks, you need four 7.5-inch squares, and four 7.5-inch log cabin blocks. To make just one 12.5-inch block, you would only need two each of the 7.5-inch squares and 7.5-inch log cabin blocks– but making 2 at once allows for mixing up the prints a bit.

I used 2 inch wide strips to make the log cabin blocks, which worked well for the size block I was going for. However, you can also vary the width of the “logs” in your log cabin for a more varied look! To start, I cut a number of 2 inch wide strips for making the log cabin blocks.


To make the log cabin blocks, start with a 2.5 inch square for the center (I just quartered a charm square for this step, but you can also use different fabrics for the centers). Then I added a 2.5 inch by 2 inch strip to both sides of the center square and pressed the seams. Next, I added the other 2 sides, and so on.



I added 2 rounds to each log cabin block, and ended up with blocks that look like this:


Once these were done, I trimmed them to 7.5 inch squares.

Next, I took my 7.5 inch blocks (the non-log cabin blocks) and drew a diagonal line down the BACK of the fabric from one point to the opposite. This is the first step in a commonly used technique for making 2 half-square triangles at once.


Place your log cabin block together with one of the non-log cabin blocks (right sides together). Your drawn line should be facing up.


Pin these together so they don’t shift while sewing.

Next, sew a quarter-inch seam on EACH side of the line. That means you’ll sew 2 lines down the diagonal of the squares, each a quarter-inch from the center line.

Once you’ve sewn those two lines, return to your cutting mat and cut along the original line you drew.



This leaves you with two half-square triangle/log cabin blocks! Press the seams open to reduce bulk, and repeat for the remaining blocks. Using a clear ruler and rotary cutter, trim each block to be 6.5 inches square.


Once you have all your HST/LC blocks made, arrange them in a pattern that is pleasing to your eye. I have been loving all of the crazy HST quilts out there, so I arranged mine somewhat randomly, and that’s what I’ll ask the members of my bee to do, too.


Sew the 2 pairs of blocks together using a SCANT quarter-inch seam. I find this matters quite a bit when trying to keep the blocks at 12.5 inches when you are done making them– a generous quarter-inch seam will make your blocks end up being a little short of the 12.5 inch mark. Press the seams open, then pin the sets and sew again to make a block that encompasses all of your HST/LC blocks.

There are so many possibilities for this block– you could match up 2 log cabins to make half-square triangles for a scrappier look. You also could use fewer log cabins interspersed in your blocks for a calmer look that still delivers some visual interest. If you look closely, in one of my blocks I used 3 half log cabins, and used a “regular” half square triangle to break things up. There are also a number of other ways that these blocks could be constructed, I simply found this to be the easiest way for me.


I can’t wait to see what my friends in my sewing circle make, and if you make anything using this tutorial I’d love to see it!

Justin's half square triangle quilt

Wow, time has been flying by this Winter! We had a great break, and were able to take a long road trip to visit family. Before Christmas, I was sewing like mad to get all my hand made gifts done in time. I barely got it all done– had to finish some binding on the road! But it was totally worth it to be able to give the gifts I made to my family.

There was one in particular that I was so happy to make this year– a quilt for my wonderful husband.

A long view of Justin's quilt

Although we have a number of quilts around the house, Justin would jokingly say that I had never made a quilt for him. I knew I needed to remedy this, so while he was at work I pieced the quilt top and back, basted and quilted the quilt, and hand finished the binding– all in the course of one week! I was careful not to let him see the quilt pieces so he wouldn’t know this was coming.

I decided to make a quilt using solid fabrics in a half-square triangle design. To add a little visual interest, I also sewed some log cabin blocks that became half square triangles to sprinkle into the quilt top. I used my left over log cabins in the back of the quilt, and I love that it is reversible. I had seen some really gorgeous HST quilts in the last year, and I really wanted to make one myself.

I love to see Justin using the quilt, and I’m happy it’s sticking around our house. One of the perks of sewing for your family!
