I should have gone there BEFORE I purchased the LED at Walmart. They have a huge selection of all kinds of LED with different brightness levels too! I asked the clerk how long a strip can one hook to a 12V adapter and he said 4ft! That's good to know!
So this morning I PIMPED my regular sewing machine with 4 x 4" LED strips. Here are some pictures:
The red electrical tape isn't pretty but it's what I have and I don't see it sitting at the other side of the table. And it matches my red chair! :)
Looking forward to increased visibility without burning myself on an extra lamp in front of the machine!
I also know where to go to get what I need for a future project... stay tuned for that one!
