60 hours of work, 1,234 4" squares, 16,042 inches of seams sewn... They are completely lined (all white) and weight a TON (good thing the song is only 2 minutes long!). And I now know how to make a reversible 25-yard skirt!
Pardon my face in this picture, that skirt was heavy, but this is it in full swirling action:
And here's another skirt, the black portion was a pre-made skirt but I added the two bottom ruffles - the bottom edge of this skirt is 35 yards around. It has better moves than I do!
