So okay. My cup-holder was your basic down-home and crappy-looking (but fine functioning) accessory. A sort of - I need it right now in the next 15 minutes kind of cup holder. What have I got around here to put one together? That kind of cup holder.
So now I have had time to do an up-grade.
Okay. Materials required: a cup collar - one of those things that allows you to hold a paper cup full of "hot" coffee without burning your hand - $cost = free (for the asking or came with your last coffee); duct tape (several colour choices available and the cost pro-rated based on the amount used) - in this instance $cost = $.63. (I.E. - Sixty-three cents.)
Tools required: my teeth for tearing the tape in the first version but a pair of scissors (second version) is recommended.
Installation time: 15 - 30 minutes. (Allow more time if you want to get really fancy/schmancy - this is where Grandma's doily could really shine; if you do not have a grandma who does doilies, maybe you could borrow one - there must still be a lot of crocheting grandmothers around; you might try www.crochetinggrandmothers.com
Functionality: On a scale of ten, with 1 being - like the guy's chrome Harley Brand holder that shook coffee all over his paint job and sparkly stuff, and which he now uses to hold his sunglasses when he parks (though, really, you can hardly blame the cup holder); and 10 being - doesn't bounce your drink/bottle/cup out of the holder onto the highway or slop all the contents around and is easily accessible both while stopped at lights and while cruising out = 9 (nothing is perfect).
Looks and style: Depends on how creative you are with scissors and tape: Version 1 = -1; version 2 = 5.
Cost/Benefit: Scale of 10 = 10.
Photos of versions 1 and 2 below. Voila!
