I found this DIY on the Design Mom blog and thought this was pretty cool. It's actually Gabrielle (of Design Mom)'s son Ralph who made these as Christmas presents for his brothers and sisters. I especially like the striped one, I think it turned out very cool.
Amal is on holiday for 2 weeks so this could be a fun project for us to do. All I need now is where to find colored t-shirts without any design on them. It's not that easy to find in Jakarta.
