That actually doesn't look too difficult! Take some beginner sewing classes and I bet you could make that within a few months if you find a good instructor We have Rec & Ed classes here that are offered at after-work hours and are fairly inexpensive.

Some of the stuff on Etsy is made my expert seamstresses and I could never imagine how to make it! I can't browse Etsy anymore because I want to buy too many $200 items
