Hi!
I really like the idea of those play mats that become toy storage bags with the drawstring. You know the ones 
Thing is, I have been only able to find either really big or really small. The big seems a standard size among different brands of 140cm across. And the small is a mere 40cm 
and no in between.
So, is the big one really a great size for legos and playing with legos?? Should I just go for it? I do have more than one child....
Do you know of a brand that does a different size?
Thank you!!
