Men Who Knit Promoting and inspiring the art of knitting amongst men.

I voted "no"
But i can only answer for me,
Wear what you like, and feel comfortable in.

OK, frank answer, how surprising!
First of all, I second the idea that lace is just a description of a number of stitches in a pattern, does not really mean it's "feminine." And, if it officially falls under society's designation that it is "feminine" because it is pink, frilly, or whatever, then so what?
Lots of people will make the assumption, right or wrong, that a man who knits is gay. But some gay men are very "masculine" in the way that this characteristic is portrayed. Some men who are heterosexual may come off in a way that seems "effeminate." As a woman, I find it offensive that anyone thinks they can judge me as a person because of what I wear or make a decision about my sexual orientation because I do or don't wear lace. And why is that anyone's business anyway? But the world is what it is, and you have to live in it everyday.
If the issue is whether you'll get unwanted attention and reactivity from members of the general public about knitted lace, then keep it to earth tones and dark colors and avoid the "feminine" yarns. Remember, there are some guys, like Prince, who have worn lace (not knitted lace but ruffled lace cuffs etc) and have been "sex objects" to some very hetero women. Guess it all depends on perspective.
Hope no one is offended by my bluntness, but personally, if you want to knit lace for yourself, that's cool and the rest of us can applaud. I will feel like I deserve applause when I finally get good enough to do a lace project!

Yes. Real men can wear anything.

Neck scarves, socks, sweater with lace panels, etc. Whatever my whimsy dictated.

Should men really wear anything at all?

Personal preference plays a lot in this. I don't mind wearing some lace items but that's just me.

I think there needs to be an "if he feels like it" option. :)
