For the Mary Janes: I worked this bootie in black for rounds 1-5. I changed to white and worked in the back loops only for round 6. continued in white for the rest of the bootie. I made the non-ribbed cuff version. the straps are just chains made long enough to reach side to side then stitched in place.

For the Two-Toned (different color on bottom)
I worked rounds 1-3 in blue, then the rest in a sweet baby variagated yarn.
