Don't be so hard on yourself. We have all done similar things...or worse. I've invested in a couple magnetic pin holders (just make sure you don't them to close to your sewing machine if it is computerized). I'm a little OCD and keep each type of pin and color pin separated (could probably get more quilting done if I wasn't so obsessed w/my pins). Auto parts stores have really heavy duty magnetic bowls but they are great for the cutting table but I keep it clear of my new machine. My old Singers I don't have to worry about.
