I had no idea what they were until I was searching the interweb for some fabric yesterday. It is a whole new language to me.
I came across Moda Bakeshop whilst looking and WOW there are so many ideas for using the above strange sounding sizes of fabric.
They even have a pdf explaining what everything is - right here
I love so many things on there and I think this might be top of the list but not in those colours as they are so definitely not me. It uses jelly rolls
or there is this which uses charm squares
and who could resist Oopsie
this is another favourite that I would consider making just for the hell of it even though I don't have a little girl or maybe my adult daughter might want a dolly to take to uni with her in september
