Since the children moved in to their bunk beds, I have been planning to sew decorative curtains that would reflect their own interests and likes. We went to the fabric store together and they picked their own patterns. I wanted to get a black sky, stars and galaxies fabric like the one I used for shirt for my son, we could only find this blue. This project, marked one of the biggest stupidities I have ever achieved. Instead of asking for feet, I have asked for yards. So we measured the bed, added the hem and cut the fabric from 7 yards for the 7-feet curtain.
I added rockets, I cut out of a scraps of this shirt I had sewn. Then I inserted long wooden sticks to the sides to hold the curtain straight (instead of hanging them from the ceiling). I had to attach velcro bands to hold the wooden stick ends to the bed posts.
I added velcro bands to hang the curtain from the wooden slats of the upper bed. Once I hung them, I showed them to the kids. Instead of happy cheers, all the hell broke loose because my son didn’t have a door on his curtain.
I guess, besides decoration, you can use these curtains to make the bed more cosy and play-house-like. That might help the transition to a new room/bed for kids who might have issues with his/her own bed.
Even if your kid is sleeping in a regular twin bed, you can sew holes to put the wooden sticks in and build a straight standing curtain like I did for the upper bed.
