With a handful of colored Hama beads and a support grid, you're ready to get started.
All you have to do is arrange the beads on the support grid, either randomly (not so easy for 2-year-olds) or by drawing a pattern.
You can also draw only the outline (with at least 3 beads wide), but the object will be more fragile.
You can use all kinds of patterns, feminine for moms or masculine for dads (for a Father's Day gift, you can use only white and black beads in a checkerboard pattern).
