As I know, Instagram is the best and the most convinient platform to sell and promote hand-made products nowadays. There is easier to configure ads, geo location and find target audience on the Instagram then on other social media. Of course, it`s not so easy to make a quality content and promote it due to high level of rivalry but this is definitely worth to do. I also want to recommend a nice web service that can help you in increasing the visibility level of your content and attracting more followers, it`s called InstaGrowing. I wish you good luck in your work. I admire people who handle with kids and work at the same time.
