Surprised daughter with room makeover, so when installed blinds which was very easy, one of the two blinds we ordered was slightly uneven at bottom. Window was level and installed blinds level, just one sat crooked. Didn’t want to hassle with returning and mess up surprise so I sewed one side up a little to fix it. Really like the blinds overall by look and functionality. Just give yourself extra time in case you need to return for manufacturing issue.
