From the hospital where we gave birth we received a diaper bag with free goodies inside. It's a good bag. It's good size and from a material that can be wiped clean. The problem is that everyone has the same bag and so those can be easily mixed up. Also it has a logo of a disposable diaper manufacturer. There is nothing particularly bad about this manufacturer, it's as good as any, but I just do not want to advertise them.
That is why I embroidered an image on a fabric and attached that on the bag. The image I chose refers to Likka's real name. I used stain stitch on the edges of the image and loosely filled the areas with cross stitches in different shades. I attached the fabric to the bag with buttonhole stitch. And that's it, now it cannot be mixed up with all other diaper bags.
