My improv piecing comes with a plan, and often a set of rules that I'm following for construction. As I work, I choose whether to follow or break my rules. Today I'm sharing my process for creating improv triangles on the corners. Along the way, I'll point out times for you to make design decisions to tailor your project to your own preferences. As always, I'd love to see what you create from the tutorial.
Welcome! I'm pleased to be joining in on the Back to School Blog Hop with Sam Hunter of Hunter's Design Studio.
Since I was working to stitch up a small sample for the tutorial I raided my scrap pile. I opted for blues, so I poured out the blue scraps to find the right sizes and values from the pile. Scraps are great for a small project, but for a larger project consider working with a pile of fat quarters or even yardage. Scraps can always be utilized for the triangles.
I decided that I would focus on the lightest value blues for the background, and my darkest navy fabrics (which was narrowed down to white on navy prints) for the triangles.
I chose two of my lightest blues that shared a similar hue of blue. The size of these scraps drove the size of my background squares. I rough cut mine into approximately equal sized squares. Obviously the background squares could be larger or smaller. You could work with a variety of sizes in one project (i.e. 3", 6" and 12"). Or you could use rectangles instead of squares.
For sewing on a triangle corner I did not precut my triangle fabric. If I had a straight edge on my scrap I used that edge. If there wasn't a straight edge, I trimmed the fabric to create one. I placed fabrics right sides together to create a triangle of background fabric showing. (This will be trimmed off in a future step.) I made sure to vary the angles of my triangle seams. Part of the beauty of improv is the organic or non-precise nature of the piecing. I gave a little thought to fabric pairings, using each navy print on both background fabrics. The triangles could be scrappy like mine, all a single fabric, or chosen to create a pattern across the quilt.
The green arrows in the photo below indicate the point where the fabrics overlap. You want to make sure that there is at least 1/4" of the triangle (top) fabric past the edge of the background square. The solid red line shows the 1/4" sewing line. Check that there is enough fabric mirror image of the corner over the stitching line, marked by the red dotted line here. You may find it helpful to hold or pin on the stitching line and fold over the top fabric to make sure it fully covers the corner of the background square.
Once the seam was sewn, I trimmed 1/4" from my stitching to reduce bulk. This can be done before or after you press the seam and trim the top fabric.
If you trim the background first, as I did, then you can trim the triangle fabric by aligning the acrylic ruler with the two edges of the background fabric.
If you trim the triangle fabric first, you can trim with the back fabric on top, as shown below. In this case you trim the triangle fabric right at the edges of the background square.
Here's my first block!
Generally with improv piecing, I repeat the process until I feel done. Feeling done can mean a number of things for me. Perhaps I'm no longer enjoying the process, I've built to a specific size, or I ran out of a key fabric I was using (though in improv, it can be very forgiving to sub in another fabric when I run out of something). In this case I stopped with nine blocks.
Once the units are created you can decide whether you want to trim them down or build them up to all be the same size. Another option would be to piece them without making them the same size first. I looked to see what the largest square I could trim to would be. If you trim them to be identical size, then the next step of completing the quilt top is a matter of combining the blocks in each row or column and then piecing those strips to finish the quilt top. If you choose to work with units that are not identical in size, then it may be helpful to work on a design wall to arrange the units in a way that they can be pieced together in larger sections to complete the quilt top. You may also find having extra background fabric(s) to add in to be helpful with this piecing technique.
My unfinished squares were trimmed down to 3 1/4".
Another variation is to stitch and flip onto the corner twice to create a double triangles, like these blocks from another project.
You can see a variety of different layout options in this post.

Nice way to do improv but not too wacky. I hope to remember this for a starting point one day...
I've got wackier when you're ready for it. ;-) Thanks for visiting, Kathleen.
