Baby and Toddler Onesie Bodysuit sewing pattern (preemie to 6yrs)

This baby and toddler onesie bodysuit called The Dylan Bodysuit is a simple and quick sewing project for a beginner sewer.

The pattern can be downloaded below.

When making the Dylan Bodysuit you have various options. You can sew them with short or long sleeves, and the closure can be Velcro or snaps.

The edges are finished off with knit binding which is very useful for a garment that will get lots of washes. The knit binding will easily iron back into shape. If you want to make your own binding the designer has included instructions with the download.
