Let it rain or snow
El hada de papel. It's one of my favourite kids crafts sites. These clouds are easily made with scraps of felt and mixed beads. The hard part was drawing the clouds. It seems so simple, but making a perfect little cloud with the right proportions isn't that easy. I googled for cloud tutorials (there must be other people having the same 'problem') and this one was the first one I opened. Once I saw that it was just a collection of circles and ovals I knew enough.
