For this project you will need two 60˝x 6˝ pieces of fabric and 38˝ of satin ribbon.
Carefully cut the rest of the fabric.
Turn shorter edges right side together and sew them.
Measure the width of your boot top. Mine was 19˝ so I cut 19˝ long ribbon piece. Adjust your machine to a strait stitch, in the longest stitch length available. 1.5˝ from the top of your fabric (the one you didn´t sew with zigzag) sew two parallel lines down the side of your strip, leaving long threads at the ends. Then take the bottom (bobbin) threads and pull them with one hand, while gently pushing your fabric away from them with the other hand. Now you have to arrange your gathers so that they are even. This should be 19˝ long, same as ribbon.
Sew the ribbon over that seam.
Now you have to place you ruffle and hot glue it to the boot.
I think, in this boots, you are going to enjoy gardening even more!
