I really took my time with these. I wanted to make sure I was doing everything properly and was trying to be as perfect as possible. I'm so happy with how they turned out (minus the uneven back pockets). I would say it took close to 7 hours. Flat felled seams and top stitching are serious business! It was my first time using top stitching thread and switching back and forth was very time consuming. But the results were worth it!
used an adorable stretch denim with a herringbone pattern. I top stitched all seams, used flat felled seams, half fly (no zip), inset front pockets and sewed size 18 months. No problems getting these over his diaper (need to try with his cloth diapers, though I hear theres plenty of room for those). The fit is perfect. I am so excited to have a pattern I can use for both kids and I can use for many years to come!
