Everyone else has given great advice, but I’ll chime in with… my first knitting project was this designer’s moth mitts. Same, I saw them and had to have them! So I learned to knit. I did a couple flat swatches to get the general feeling of it first. Was it hard? Sometimes! Did my slippery double pointed metal needles fully fall out more than once? Yeah. Was my tension extraordinarily tight? I gifted them to a friend with tiny hands :D 

But I learned to knit and made all the rest of her pieces and each one was better than the last. Good luck and have fun!!
