This is a project I completed for Aussie Scrap Source for their Make it Yourself Series in March.
I elected to do quick and simple stamps. This would be so easy and fun for you to do with the kids.
What you will need is;
Craft Foam [I got mine from a discount store]
Acrylic stamping block
double sided adhesive tape
To seal the craft foam stamp top prevent it soaking up too much ink seal it with the glue stick and allow it to dry :)
Ink and stamp away to your hearts content!!! :)
Cheers and happy creating :)
