Some day my son will be mad at me for having this picture of him in a pink and purple poncho, but my daughter would have been too big for it and I made it to give as a gift. The poncho pictured is how I gave it with the added pocket in the front and the purple collar, but below you can see what the poncho looks like if you just want to cut it out and do a no sew poncho.
Supplies needed - fleece and scissors and a measuring tool are all the basic supplies you need to make a no-sew poncho.
First I measured out to make a 24" square out of my fabric. I will later cut the edges, but it is easier if you cut down your fabric to square to begin with.
Using a bowl that fit on my toddler's head, I placed it in the center of my fleece and cut around it.
Here you can see how it drapes around him when left as a square, which you can certainly do. But I laid it down and rounded off the edges.
With some leftover fleece, I made a pocket for the front. Toddlers love pockets!!!! Of course, this you will have to sew on, but I wanted you to see it so you could see the measurements and how I cut it. The piece is folded here.
