Here’s a quick simple blouse I was able to put together in less than an hour using a pre-loved sarong from my closet. I took advantage of the finished edges for the seams on the side and folded them in to make a width of 33 inches. Depending on your height, you cut your length. I’m short, so I made mine 46 inches plus an inch on seach side for the seam. What I cut off on the bottom of each end, I used as a sudo bias tape to sew around the collar.
After folding it in half, I cut out an opening for the neck. For the armholes, I just pinned and sewed two lines 10 inches down from the top to the bottom. Finish off the hem by folding in twice a 1/4 of an inch and sewing down.
