This is Tilli and Meggies' Christmas gifts. Fluffy knitted Christmas balls.
This is the balls I am using for the centre. They are 18 cm round and cheap! $6 on ebay for 100 balls, light weight hollow plastic for play pits. I am using them for next years thank you gifts. Some will be knitted, some crochet and some with fabric and felt. Some will have embroidered and cross stitch panels too.
