The work continues

I am currently working on a baby blanket for someone. I had given them a quote of how much it would cost based on the required amount of yarn and intricacy of the pattern. Well I am nearly half way through part 2 of the project and it is taking more yarn than expected. If you were in that situation what would you do? Well I spoke to the customer. Explained my dilemma, gave them 2 options.
1. Pay pre-quoted amount for smaller blanket or
2. Pay recalculated amount for full size blanket.
Well she chose option 2 so I am looking forward to seeing the finished product by the end of the coming week.
