For the ends of the scarf we will use the Solvy in a slightly different way.
Instead of running it with the grain of the yarns, for the end we will run it perpendicular. Cut a length of Solvy two times the width of the scarf, so for the 7” wide scarf, you will need a 14” piece. Place the Solvy on the table and set the next section of bare yarn on top of it, just slightly overlapping the part already sewn with Solvy.
Fold up the ends of Solvy (like wrapping a present) and use several pins to hold them in the middle. Sew this section in the same way you did before. Repeat this entire process with the other side also.
