crochet animation. Text: Fashion School - Crochet - A type of stitching created by looping yarn with a small crochet hook to make pieces of fabric. While it's been around for decades, crocheted styles reached popularity in the early 1900s, before finding its peak in the '70s (think: brightly colored ponchos or dresses). Today, the look is a warm weather staple in more minimal pieces - find it accentuating blouses, sprucing up lace dresses, or trimming summer tank tops.
