This is a great, easy pattern for 5 basic shawl shapes: Square, Circular, Triangular, Semi-Circular, and Heart-Shaped. http://www.laylock.org/?s=5+basic+shawl+shapes
Each style begins with casting on three stitches and is worked to a full-sized shawl or stopped at any point for a smaller scarf, which I did. The pattern calls for garter stitch but can be made in any stitch or pattern you choose (be sure to knit 5 stitches on each end of each row to keep edges from curling). The size will depend on what yarn/needles are chosen.
I made a child’s size triangular scarf out of scraps of baby yarn (above) and an adult sized scarf with a vintage button added.
Note that the scarves are worked top-down and the beginning three stitches will form a part of the top of the scarf.
This is a fun project and a good way to use up small amounts of yarn.

These look so soft! The second one with the button is my fave.
Interesting that you can get such alternatives using the same pattern a little differently. I like your finishes, and no doubt a child will love the colors in that one.
Thanks. These are pretty.
