DIY Blackout Curtains: Semi-tutorial

With all of the crafting I’ve been doing lately, it feels so strange when I don’t get a chance to work on anything for the week.  In fact, I feel guilty if I don’t get some practice in.  I know I’ve still got a ways to go, so I feel like I should be getting practice in daily.  Between work and personal time, it isn’t always possible, or even practical to craft a lot.  

Last month’s craft to-do list was a little bit long, but I’m happy to say I at least finished a little more than the previous month’s list. I still need to increase the time spent making things, so I know I need to get more control of my scheduling/time management.

One of the things that I enjoy most about crafting is when the finished product is a functional piece to the home, office, or wherever necessary.  After finishing the curtains for my fabric storage shelf, I wanted to finally tackle the blackout curtains I’ve needed.  I originally wanted to make all new curtains, but I decided I’d rather save the money and just repurpose the existing curtains.  It’s also a cheaper option than buying pre-made blackout curtains.

**This process will also work for any lining you want to add to an existing curtain panel, not just blackout lining.

I picked up some Roc-Ion Blackout Lining Fabric from my local Jo-Ann Fabric.  It could technically work as either a main fabric, an attached lining fabric, or a second layer that just hangs behind the main fabric.  I chose to use it as a lining fabric directly attached to the main fabric.  Another benefit to using the existing curtains is that you already know the finished dimensions needed, and the hems are already pressed into the fabric for easy guidelines.

I unfortunately didn’t take any photos of the process because I originally wasn’t going to post about it since I wasn’t really “creating” anything.  I figured it might help someone else out who’s looking to make their own blackout curtains, so I’ll try to write out as many details as possible.  

**Disclaimer:  I’m in no way a professional, and this is certainly not the only way.  It may not even be the best way, but it was easy and worked for me, so hopefully it can help someone else!


Begin carefully seam ripping all of the existing sewing lines from the manufacturer.  This will give you one large rectangle of fabric (as if you’re starting from scratch).


Length:  Cut about 2″ less than what the FINISHED curtain length will be.  For example: if the finished length from top of the rod pocket to the bottom hem measures 60″, cut the blackout lining to 58″.  This will make sure the raw edges of the lining are encased within the hem while reducing bulk for sewing.  It’s not vital, you could still make it the same length of the main fabric, but it may increase the bulkiness when sewing the hems.

Width:  Cut 1″ less than what the TOTAL width of the main fabric measurement is (the measurement from side edge to side edge after seam ripping).  We’re cutting it shorter to create a self-binding effect that will hide the raw edges and keep the blackout lining from rolling to the front of the curtains.

3). SEW IT UP!

Place fabrics right sides together.  Line up one side seam, pin.  Since we cut the length of blackout fabric shorter, be sure center it in the main fabric so that equal amounts of the main fabric are at the top and bottom.  

Sew side seam only using a 1/2″ seam allowance.  Repeat along the other side seam.  Do not sew top and bottom seams.


Turn fabrics right sides out, press.  You will start to see where the front fabric naturally pulls towards the back, creating a border along the sides.  Pin side seams if desired and topstitch.  Repeat with other side seam.  This creates a really nice, professional finish to the backside of your curtain.


Now all that remains is to fold down the top to create the rod pocket, and fold up the bottom hem.  Use the manufacturer hem lines as a guide and it will make life so much easier.  When you fold and press the main fabric towards the back, it should cover up the raw edges of the blackout lining.  If for some reason it does not, give yourself more slack in the seam allowance until the lining is covered.  Pin and topstitch in place and you’re done!  Repeat process with any additional curtain panels you may have.

I love that there are no raw edges exposed and that the lining and main fabrics work together as one unit.
