Bibs
So easy to make, easy to sell, every kid needs at least 3 (haha at least)
I like to make them with a waterproof backing(super good for dribbly teething bubs), same as used in modern cloth nappies and a metal snap dome on the back. I think I may start doing 2 of these domes so they can fit a range of neck sizes

 

These were all custom orders hence why they are ALL girly as. I am in the process of making boys ones, skulls, bugs and such. I'll get back to them some day
