STITCH & FLIP
Stitch and Flip corners are easier for me than cutting and sewing triangles, so I use this method for the inside of the dandelion block. Here's a brief tutorial:
The next two pictures show how I sew the stitch-line... not directly on the chalk line, but just a hair to the outside of it. This is because when I go to flip the corner out, a tiny bit of fabric will be taken up in the fold and the resulting triangular corner will be a little short. Sewing just a hair into the seam allowances gives me that tiny bit back.
Trim the corners off a quarter inch from the stitch line, and then flip the yellow corners outward and press. In the picture, you can see I pressed this seam open rather than to one side; that's because my two fabrics were both light colors and I thought it would reduce seam allowance show-through. Later, Rosanne informed me that I need not have worried about that: once there's batting and backing, it all blends together. If you have darker fabrics or more contrasting fabrics, you should press the seam allowances toward the darker piece. However you decide to press, be consistent for every unit and all nine dandelion blocks.
Since my quilt calls for nine dandelion blocks, I make nine of these units.
The seam allowance that I trim off gives me a thirty-six right triangles, already conveniently stacked as if for sewing. So I sew them! I don't know what I'll use them for, but perhaps they can be a detail on the quilt back. I play around with arrangements.
PIECES OF EIGHT...
...eight half-square-triangles, at least! Each Dandelion block calls for eight HSTs of the two shades of yellow, and eight HSTs of yellow/green. I sew them in a rather clever way I saw on Pinterest.
Here's the same process with green/yellow HSTs. The contrast in colors is stronger, so you may prefer these pics, though the whole process isn't documented.
Here's the various units of the dandelion block, all laid out, then sewn together. So pretty!
