What you need to remember is that with stick models, the area being covered is considerably less than what you're trying to cover in this build. Most use the supplied tissue to cover the model with so a little water tightens it right up. Along with the dope needed to hold the tissue to the wood, there's not a lot needed to cover with. I've built several Guillow's planes and, other than not breaking the sticks, putting your finger through the tissue is the hardest part
