One continuous piece of fabric long enough to lay out the Thousand Chain--no seams! So many Montessori students have only seen the Thousand Chain laid out in a spiral and have missed the dramatic impact of the length of the beads all in a row.
This durable mat is made of soft, 100% poly-fleece. It rolls up neatly for storage and can be secured with the attached elastic band. Machine wash and dry.
It may also be used partly unrolled for the other cubing chains. 30 feet long x 9½" wide.
