Big time, yes. Every time. Nothing says I love you like a home-made jacket or video console system. But seriously, there is an inherent sweetness in receiving something that was conceived and labored on by a sweetheart. It doesn't have to be Martha Stewart perfect to be perfect. In fact botched cakes, crooked crafts and 3-legged stools are the gifts a man will remember long after he dumps you.
Anyone can go to Best Buy and put an iPad on their credit card, but only you can make him a shelf out of last summer's seashells, so that he might have somewhere loving to rest his inhaler and Viagra.
Any man that gives you crap for gifting him with a personally made piece of crap is a piece of crap himself.
Yeah, homemade gifts work great...my ex still talks about my baking and periodically makes requests.
Go for it, if he's into you he'll find the gesture sweet and endearing.
