Hello.
Pat's photo shows exactly what "Inside Out" looks like. It is like a nest. Onesies are a lightweight knit fabrication. They will have to be secure on your hoop in order for them not to shift. A mesh stabilizer would be recommended for baby's items. With mesh stabilizer, the items stay soft; especially needed when next to baby's skin. For some reason, I also place a Water Soluble Stabilizer on top of the onesie. To me, it just seems to work out better.
If you feel intimidated by this method for the first time, another way to embroider the onesie is to have a design on the rear; basically where the baby's bottom will hit. Especially cute for the "crawling crowd". With this method, you will get the feel of the fabric, etc.
