Good for you for trying something new.
Wool can be quite stretchy, so you are smart to be thinking ahead, before you get into it.
I am sure you are not the only one in your Guild that will be new to working with wool.
I would hope that if a Guild is starting this as a new project, that they will be taking the newbies into consideration and will be providing the help needed, with each BOM, in order to complete it.
Otherwise, I would fear there will be a lot of frustrations ..... and perhaps abandonment.
