Roughly divide the prawn mixture into 12 portions. Shape each portion into a rough shaped ball and place into the wrapper ribbons.
Scoop the ribbons around the prawn mixture and shape into a ball, squeezing lightly with your hands to secure the ribbons on the outside. (You can trim overhanging ribbons off and return them to the bowl to use again).
Place onto a lined baking tray. Repeat with remaining prawn mixture and wrapper ribbons. Cover and chill until ready to cook.
TIP: Save any leftover 'ribbons' to quickly deep fry after cooking the prawn balls. They are lovely and crunchy and nice to snack on. Discard though if preferred.
