I cut them off at the knees and opened up the inside leg seam, and both side seams below the pocket. I used the bottom portion of the legs that I cut off to cut four triangles (two large for front and back and two smaller ones for the sides). The crotch area on the front and back has to be cut back to form a relatively straight line from the waist band to the bottom of the leg. Insert the triangles. Put a ruffle on the bottom of the skirt.
Then I appliqued flowers to look like they were coming out of the pocket on the left side, and across the front.
