'Magnetic Mosaics' is a great rainy day activity, or heatwave activity as the case may be in these here parts.
Unlike the sticker type mosaic crafts you can buy, this one uses coloured magnetic foam pieces, a sheet of predesigned numbered paper and a magnetic board which can be used over and over again.
I find this activity often helps us all relax when we sit down to work on a design, plus Miss 3 can practice matching the colours to numbers.
It's definitely a winner at our place, though if you have a baby or small toddler, take care with the small cubes.
You can buy it here at IQ Toys although we were lucky to find this as an Op Shop Treasure :-)
