All it took was a little work with a seam ripper, and I was able to make them look like this:
Ignore the fact that I haven't ironed it, but you get the jist. All I did was take the hem out of the top and bottom of the curtain. I have yet to re-hem the edges up a half inch, but all in good time. Here's a close up of how much extra length I was able to get out of the top and bottom:
Almost a solid 3 1/2 inches.
Want to know my other secret?
Giant rings from Target (at $6 per pack, so $12 total) which lengthened the curtains another 2 inches for me.
There you have it, how to effectively destroy high water curtains. You would need to make sure before you bought the curtains that there was enough hem to take out - not all curtains are hemmed to ridiculous heights like mine were.
And the board and batten? Soooo close to being finished. I will discuss in that post why it took me almost 2 weeks to finish what should have been a weekend project. Hint - it has to do with having a 3 month old.
