Stuff to Know
You'll need a ruler with a 60-degree line marking. My ruler has two markings that go in opposite directions. I'm using a 12" x 6" ruler, and sometimes a 24" x 6" ruler. A 60-degree triangle ruler comes in handy for cutting triangles, but it isn't necessary.
Even though you can use triangles to build your blocks, this isn't really a triangle quilt. I sew random pieces together, then trim, and most of the triangles just appear accidentally. I don't worry about it, but if you want to know how to get a point, look for the * below.
I press my scraps before sewing so that I don't have to do a lot of pressing after I sew. Because a lot of the edges are on the bias, I don't want to press any more than necessary. If you ever thought about using starch before you sew, now might be a good time to try it.
The picture follows the instruction above it. I made the pictures a little smaller so the page won't take forever to load if you don't have a fast connection, but you can click on each picture to enlarge.
Cut A Few "Starter Pieces"
Begin by cutting a few 60-degree shapes from your strips. Not necessary, but it gives you a place to start. The size of the strips doesn't matter. Use an assortment so you'll have a variety of shapes. Place the 60-degree line of the ruler along the bottom edge of the strip, and the right edge of the ruler on the bottom corner of the strip. (I've highlighted the 60-degree line in yellow so you won't have to look for it.) Trim.
Place the 60-degree line of the ruler along the bottom edge of the strip, then trim the other side. I used the whole piece of fabric for this one, but you could make two shapes if you like, or even make a diamond shape.
Now make a few triangles. Again, the size doesn't matter. You'll end up chopping off a lot of the points anyway. I just find it easier sometimes to use triangles rather than bigger chunks of fabric. Make lots of sizes. And don't worry if you chop off some points -- the 60-degree angle is what matters. Place the 60-degree line of the ruler along the bottom edge of the strip. Trim.
Rotate the strip so the trimmed edge is on the left. Place the 60-degree line of the ruler along the top of the strip, and the edge of the ruler at the bottom of the strip. Cut to make a triangle.
To continue cutting triangles, place the 60-degree line of the ruler along the bottom edge of the strip and the edge of the ruler at the top of the strip. Cut to make another triangle. You can continue cutting triangles, or you can save the leftover piece for later -- it already has a 60-degree angle, and you'll find something to attach it to later.
Here's an example of some 60-degree shapes and triangles.
Let's Put Some Segments Together!
Below is an example of how I might construct a unit. Since you'll be working with different sizes of strips, don't worry if yours doesn't look like this one. Start with one of your 60-degree shapes or a triangle, and sew a strip of fabric to it. Press in either direction. Place the 60-degree line of the ruler along the bottom of the triangle or shape. * Now I'm going for a point at the bottom of the green fabric. Make sure the quarter-inch line on the ruler intersects with the seam about a quarter of an inch from the bottom of the triangle. (Hope that makes sense.) I've marked a yellow X below where the ruler marking and seam should intersect.
Sew a triangle or chunk of fabric to the bottom right corner. 60-degree line on the bottom; trim on the right.
Rotate so the yellow triangle is on top. 60-degree line on the bottom; trim on the right. And now you have a little segement. I like to make lots of segements to combine in different ways.
Let's do another one! Sew a couple of rectangles together. Place the 60-degree line of the ruler on the seam line, and the edge of the ruler at the bottom corner. Trim.
Now trim the other side. (I'll stop telling you now where to place the 60-degree line -- just make sure's it's on an edge or on a seam.)
Add a strip (green here). Trim the right.
Rotate so the strip is on the bottom. Trim the other end of the strip.
Sew a strip to the left side of the unit. Trim.
Rotate so the strip is on the bottom. Trim.
How we have two segments. But they're not quite the same size. No worries. Just decide which of the points on the largest triangle unit you'd like to sacrifice. I decided to sacrifice the green on the left since the strip is wider.
Sew the triangle units together, maching the bottom corners. You'll have excess fabric on the top. Trim off the excess.
Now sew something big (a large strip or a large triangle) to the right side of the unit. Trim.
Rotate so the bottom of the unit is on the right. Trim
To finish out the point, add a little piece of fabric. Trim.
Rotate so the bottom of the unit is on the right. Trim.
I had a 60-degree shape already cut, so I added it to the top. Trim the right side.
Rotate, and trim the other side.
To finish out the point, add a small chunk of fabric. Trim on the right.
Rotate, and trim on the left.
Now you have a finished triangle unit. Just keep making triangles and don't worry about the size. I'll be back later to show you some filler units and how to make it all fit together.
To keep from having to post another hundred pictures, I made a collage showing the progression of a different block. Maybe it will help to see it put together step by step. Pictures are shown before trimming and after trimming.
Hope you'll give it a try. It's so much fun! I'll be back later with more.
