One place that all new trends are implemented right away in a creative manner is etsy - online shop for vinage and handmade. I love to browse there to buy or just for inpiration. There are some items with geometric forms that I included in a Treasury list, called 'I love geometry / Presents for everyone under $20'. As you see the geometric trend in in jewellery, cloths, textile, interior, decoration, fashion acesessory and ect. You could use them as shown in part 1 of the post or just enjoy!
