When my husband and I first got together I was crocheting an afghan. He complained THE WHOLE TIME I was working on it, probably because he felt it took my attention away from him.
But I just kept working and finally it was done! Yay, Yippee! I laid it over the chair and went out to the kitchen to get myself a cup of coffee and by the time I got back he was rolled up in it like a windowshade, sound asleep on the sofa!!! He totally took possession of the thing but the upside was he stopped complaining!
Now, over 30 years later, he spent most of the winter curled up in his recliner under yet another afghan I made!
It might take some time, but they usually do come to appreciate your creations!
Good luck with that!
Meanwhile, happy knitting!
