We use these shades in my son's nursery and LOVE THEM.  They really are blackout shades, come in multiple sizes (work on my "non traditional" window sizes), and look fantastic.  I was ready to shell out a ton of money for custom shades, since I couldn't find the right size - but no need!  These are perfect.  Have had them for over a year now.  We had a slight issue with one of the shades (a string broke on one of the three shades we own) - but thanks to amazing Wayfair customer service, we had a new shade in no time.  Can't say it loud enough - don't spend crazy amounts of money on custom shades - these are wonderful.
