Double Crochet
Wrap again and pull a loop through the 2 loops on the needle. Finish the row; turn the work; and make another row of double crochet stitches.
To Make Slip Stitch
Make 15 chain stitches. Skip one chain. Put the hook through the next chain stitch; wrap yarn over needle, and draw it through both loops on the needle. Continue to make slip stitches to end of chain. Turn the work, and make a second row.
As you may guess, Mary Frances had very little trouble in making these stitches, for Crow Shay was a wonderful help.
