Its quite a big bigger. When I made mine I had a complete ball left over to return to the store so I told her I thought the pattern overestimated the yarn requirement. Well it may have been the case for my gauge but not for hers. She finished the bag itself but now will in fact need the whole quantity stipulated in the pattern in order to complete the project by making the bag's "rope" handles.
Its a real eye opener for me to see a demonstration of just how much gauge can impact the amount of yarn consumed by a given pattern!
Happy weekend everyone!
