You can use any yarn weight or type, with a suitable hook size to make your mini poncho. The yarn and hook size you choose will determine the finished size.

As a guide, I have used Paintbox Yarns Simply Chunky (US Bulky), 100% acrylic yarn, with a 6mm crochet hook. My finished poncho measures approximately 19cm/7.5″ long (front to back hem excluding fringe), by 12cm/4.75″ wide, with a head opening of 6x5cm/2.5×2″. The fringe can be trimmed to any length to add to the total length of the poncho.

I have used a mix of 6 bright colours (Red, Hot Pink, Blue, Green, Yellow, and Orange). You can substitute colours as you choose. Keep to the same yarn weight throughout, and try to keep to the same yarn brands for consistency.
