I knew a woman years ago that homemade was not only not using blue box mac-n-cheese you couldn't use the a box of noodles either you had to get the flour out and make your own pasta. By her standard I probably never cooked a "homemade" meal. Truthfully she rarely did either because everything took her hours she fed her family fast food at least twice a day probably 25 to 28 days a month. but that's a whole other kettle of fish.
So my theory on food is canned soups, boxed meals, boxed cakes and cookie mixes made following the directions with no variation are all home cooked. Any of the above items used as a base or ingredient making your own dish is homemade.
As far as crafts and quilts if I put it all together I made it if I used a precut quilt kit I still made it I just utilized someone else's skill of color and cutting, and yes I consider using a friend or professional LA to quilt it as homemade I'm utilizing a skill that someone else has....if I find a plain frame and decorate and give it I utilized a premade base for my "artistic" design.
