It is my first wooden model boat and I don't suggest this kit for beginners.
1- Formers need to fill with shaped wooden sticks to fill the gap between formers and sideboards. If you don't fill that gap, then you need to reshape sideboards -sand to form to a crescent shape- but in that case shape of the sideboards will be wrong.
2- It is helpful for learning clinker type of planking, but it is difficult because shaping the 1,5 mm sticks is hard work.
I made a template to cut 1x4 mm sticks for bow and stern frames. These frames must be done before planking. Because sideboards are glued on hull then it will be difficult to cut the frame sticks in exact size.
