Kaleidoscopes and Mandalas are not the same. Yet they are so much alike to me I use the terms interchangeably.
Usually I gear them towards making quilts but have found them to be quite versatile in decorating other type projects.They create beautiful scallops along the edges of pillowcases, sheets, tablecloths, and garment hems.
Traditionally when used in quilts they are used as blocks, corners, and borders. However, they can be arranged anyway you desire. The possibilities are limited only by your imagination.
