When I first started knitting 5 years ago, when people complimented my projects, I usually would respond saying that it's really not that hard and I wasn't doing anything special and anyone could do it if they tried.
Even when I started making more complex things, I still maintained that my knitting was nothing to write home about. My stitches were even, but aren't everyone's stitches even? (Apparently not.) I'm knitting on 4 needles? Really, it's not that hard. "Ooh, that's such pretty yarn!" I have good taste in yarn. But really, how much creativity do you need?
(The exception to all of this is compliments from the people I made things for. Of course I'm going to be happy that they liked whatever I made them, and I'm glad they appreciate)
I think I got better about accepting knitting compliments when I started spinning, since spinning is less common than knitting (though in my opinion it's not harder.) And I think at this point I'm okay with people admiring my knitting. The Celtic cable scarf I'm currently working on is the nicest thing I've ever made. And it's relatively complex.
It's about halfway done. Here's a more recent photo:
I'm really proud of it. And the person who it's for has seen me working on it, and really likes it. And he's impressed by my spinning, even though it's far from even.
