Except that it's becoming increasingly co-opted by commerce. How many non-commercial "maker" events are there? Make Magazine and various others are explictly selling the maker ethos, and using the maker "brand" to sell other things.
Michael's also sells more than just the literal stuff in their store - they sell the entire notion of doing things yourself. It's no different. All it means is that "man crafts" have caught up to "woman crafts".
An illustrative division would be: Micheals is predominantly "woman crafts" in that the main portion of the store is devoted to the classical archetypal "woman work" like knitting, crochet, decorating, etc. Yes it sells the entire notion of DIY. I think last I was in there was one isle that was classical "man stuff".
However, the main store behind the notion of DIY for men is Home Depot (and the other hardware stores). The inverse is shown here where the décor section usually takes up one isle.
We need to stop assigning gender roles to activities. I have a 20 month old son, and me and my wife try very hard to not genderize behaviours or activities.
The difficulty is getting everyone else around you (especially grandparents and other family) not to do the genderizing. It almost gets to the point where I'd rather they not interact with my children.
