Pink and red are huge colours this and even But tieing them together with soft aqua is really fresh. It works because blue and red are primary colours (and complimentary). Aqua is just a soft version of blue.
Maybe cut up a felted jumper to make this, or if you have the patience, pick up the stitches (unfelted) and cast off . could even crochet into the cut edge (Knitting Relay). Add a pretty shirt to complete the look!
