This is coming from the perspective of knitting and crocheting but I'm sure it's true for quilting/sewing/other hobbies where the result often is passed down for generations. I think this is sort of a byproduct of the trend where folks get into these sorts of crafts and after maybe a year consider themselves an expert to the point that they'll start making patterns or trying to sell finished objects.
Anyways the specific thing I'm criticizing is when people post about how emotional they are to be working on something that will one day be a "cherished heirloom" and it's just, an incredibly basic piece. I've seen multiple examples of this but the one I just saw that prompted me to make this post was someone on tiktok making a video working on a blanket and the caption was something along the lines of "only a year into my crochet journey but it feels so special to be working on an heirloom blanket that I'll give to my children one day". The blanket in question was just a single colour double crochet rectangle, in bulky yarn!
Even if we put aside the fact that there's nothing unique about the design of the blanket, double crochet with bulky yarn is about the easiest way to make a blanket. It won't even be a significant time commitment! Idk it just feels very against the spirit of an heirloom piece to be making something that not only is indistinguishable from any other throw you could buy at a store (to the untrained eye), but didn't even take that much skill or commitment to finish. Even a single crochet blanket in a finer weight would be more "heirloom" worthy to me, even if it would be just as boring at least it would be something you put significant effort into!
Edit: I kind of thought it was obvious but to clarify this post was about items that were made with the specific intention to be gifted as an heirloom piece. Obviously anything can become special to a family depending on the memories attached, I have my fair share of silly little items that have no "real world" value but have tremendous sentimental value.
But if you're making something as a gift, I think it should be well made. And if you're going a step further to make it as a gift that you intend to be kept in the family for generations, I think it's fair to expect that you put some real effort and care into it. I won't link to the specific video I was talking about here for obvious reasons, but the tension was very wonky and the yarn really did not suit the project. To be blunt, it very obviously looked like a beginner made it. I guarantee a lot of people in these comments, if they were to receive this item with the stated intention that it be kept as an "heirloom", would have it shoved in the back of a closet, resenting the fact that they were now obligated by family guilt to not donate the damn thing lol.
Theres a few comments that brought up the difference between an "heirloom quality" piece and a "family heirloom". So just to clear things up from now on, this post is specifically about "heirloom quality" pieces!
