The spacing of the yarns is quite small. I ordered the framework for my 5-year-old, the weaving was a lot of fun in kindergarten. I wanted to string every second cavity so that it has more distance during weaving. But that does not work because I will not hinkomme with one of the bars. (The poles are to be a great thing. They prevent the children put the woven too tightly and they hammer out so not a straight line)
