The Dawn nylon pompadour is a fingering weight yarn, that has 133 yds/oz. (http://www.vintageknits.com/vintyarn1.html) The all nylon has 136 yds. Dunno about the tucking and sewing.
That is really cute! The tucking is simply folding your “material” and tacking it so that the fold stays. Just use the picture to guide how it will look. I think you will find it easier than you think.
