I thought it was only me. I have that problem. But I found that if I look for something else, guess what, I find the first item I was looking for. I have started to put the item found in a safe, standard place, a basket on my sewing table, so when I get back to the project I need it for, I can find it. I thought age is causing this but maybe I am just too busy and not together.
good luck and hope you find what you are looking for.
