A week later, this is what I ended up with:
And here's a closeup of the cute cabin-themed fabric:
While sewing your own clothes, draperies, etc, is no longer always the cheapest option, sometimes it still is. For example, when you can get the fabric for free (say, from Freecycle) or deeply discounted (such as at yard sales). And if you want something very specific, as in my case, sewing your own stuff can also bring much greater satisfaction because you don't have to settle for something less than what you imagined. What you make yourself can also be of better quality, as so many items you see at the store these days are made from inferior fabrics.
Not to mention, there's a certain pleasure in doing the project yourself, and a feeling of accomplishment when it turns out well. As far as self-sufficiency goes, knowing even the basics of sewing definitely brings peace of mind.
