I said I would and look! I actually did: I made summer pajamas from a bunch of thrifted tees.
And the kids actually like them! There is no Iron Man or Perry the Platypus or Elmo or whatever character they're into this minute in sight. I'm not against the odd licensed character, but I cannot deal with the weird, plastic, pajama fabric they are printed on. When they're new the fabric feels like slimy alien skin, and after a few washes it turns into pill-y, old, molted alien skin.
Obviously I have some issues with kids' pajamas. Not these suckers though! They are all 100% handmade from 100% second hand clothes.
Here are all the sewing details:
fabric: thrifted tees pictured here
pattern: For the shorts I used the sleeping johns pattern from Growing Up Sew Liberated. I made the sleeping johns a few years ago and they still fit my daughter. So the fit is obviously pretty generous. My 7 year old daughter is wearing a size 5T, my 6 year old son is wearing a 4T, and my 3 year old son is wearing a 3T
The shirts are made with Rae's Flashback Skinny Tee pattern. The only time I actually followed the pattern was for the gray shirt in the middle. For the other two shirts I used the pattern more as a guide. The tank top is far from perfect, but it works for pjs.
sewing: The shorts went super fast and were not a problem at all. The shirts were a bit more fiddle-y, because I chose super soft, super thin material. My sewing machine prefers to eat material like that rather than sew it. Arg!
The plan was to have two pairs of pjs for each kid, but only the youngest got two (the second pair is pictured above). For that gray striped top, I used Kristen's Flashback Tee --> Tank Top tutorial and blatantly copied her style while I was at it. There are two more pairs of pjs in the works. Both are half done, but I think I hit a pajama making wall. Maybe I'll climb over it this weekend :)
