Cardboard Mosaics Round pieces make for a fun, easy and effective decorative craft activity. These Cardboard Mosaics Rounds are sturdy, lightweight, have a matte finish, and are in two sizes. These round mosaics are double sided – a bright colour on one side, and black on the underside. To use simply glue them onto your surface using PVA or a glue stick. Create beautiful and colourful artwork on cartridge paper, Papier-mache boxes and gift cards. This collection of rounds can also be used as maths counters, and as a decorative 2D embellishment.
