If they're useful as you work with Bubble Groups:
 
	
Elastic Rings to support small groups to focus and play
	
measured to be big enough for a Bubble of 6, plus a practitioner, to play and be 2m distanced
	
OR 12 at 1m distanced (usually 23+)
	
7 different plain colours on each (a colour for each person perhaps?)
 
	
and if not for Bubbles, then all those fabrics make them very jolly!
