Where to learn how to do a manicure? ?

I don't do my own manicure, but find ideas for short coffin nails on https://naildesignsjournal.com/short-coffin-nails-design-ideas/ and ask my master to realize it. In general, I love this site, because it tells how to combine colors and design elements to make the result look harmonious. I highly advise you to check it out if you want to try something bright, but not too flashy!

I have always admired beautiful manicures and love experimenting with designs, but lately I just have no inspiration. Everything I see seems either too complicated to do on my own or already boring. Where can I find really fresh and creative ideas for manicures, so that it is not just copying other people's work, but something unique? Maybe there are some trends that are easy to adapt to yourself? I would also like to understand how to learn to do a good manicure on your own. What tools and materials are needed for this? Is it possible to achieve a neat gel polish coating without expensive equipment and courses? Please share your experience - who started doing manicures themselves and eventually reached a decent level? What techniques are the easiest to master at home?
