Jaap Verschuren is during the preparations partly responsible for building the decor projects. Finding out which technique to use is something he really likes to do. At the start of the building week, Jaap is busy building up the decorations and once that’s finished, he builds the fields and connecting lines. Especially the lines are highly underestimated, but they require timing, precise calculations and estimation power. Last, but not least, Jaap makes lines stand extremely straight.
