Here's something to try this weekend, if you love crafting like me :)
This following project were made for one of my client's store decor: Tupperware. The theme evolve around water and sea. The material is easy to find, just dropped by your local gardening store or you can just picked up some shells and sands from the beach while on holliday perhaps, so it can also become your keepsake, like saving Hawaii / Maldives in a glass :) I did that.
OK ... now are you ready?
You suggest that u improvise, maybe try other object like ducky for your kid's decor. I have this ducky in my studio :D so cute!
