This is a free pattern from the blog ikatbag.com by LiEr - a very creative lady who works wonders with fabric and also with cardboard - to dress her kids and to keep them amused respectively. Thank you, LiEr!
It is meant for a 3 year old, but my 2 year old looks fairly comfortable in them. LiEr suggests piping around the pockets but I added some different decorative elements such as zigzag stitching in a contrast thread and a purchased label on the back. The first one I made was a trial version and did not have pockets. The buttonholes are on the straps, a mistake I rectified in the second version. Fabric is recycled adult jeans for the first ( trial) version and a sturdy denim for the second ( about 270 rupees per meter at Parthas , I bought 60 cm of 150cm wide fabric ).
