Hi Leanna,
Your WI climate won't be too different from our CO one, and I compost all through the winter.
Here's my method:
I have a compost collection bin in the kitchen. I've tried plastic and don't like it because you can't clean it properly. I use stainless steel bathroom waste bins - the all-in-one construction types, no seam between the sides & bottom to collect stuff. I got mine for $4.99 from Ross Dress For Less, and I got another one from a thrift store for a similar price. I took it to the thrift store (talked to the cashier first!) and matched it up with a glass lid, another $1.99. It's probably about 8 qt capacity (8 litres). Since you're in America's dairyland, you could use one of those beautiful stainless steel milk buckets, expensive but very very nice.
You don't need the bins that have the charcoal filter in the lid since you'll be emptying the bin before anything gets smelly, or if it's smelly, you take it out to the compost heap ASAP. (I have a separate bucket in the kitchen for waste water.) If you keep your indoor compost collection bin as dry as possible, it won't smell.
Since the more cut surfaces there are, the faster that things will decay, EVERYTHING that goes into the kitchen bin is chopped/shredded/cut/torn into SMALL pieces. You can add: eggshells, peanut shells, pet hair, mouldy bread and shredded/torn used paper towels, paper napkins, coffee filters, as well as coffee grounds & tea bags.
Your Valentine's Day flowers are probably getting a bit tired by now and into the compost bin they can go, all nicely chopped up into those SMALL pieces. If you've been washing pet bedding, you can add the hairy lint from the dryer. Also add the human hair that you clean out of the hairtrap in the bathroom, or clean out of your hairbrush.
That takes care of inside. Very simple.
In brief:
Chop everything
Have a lid
Empty frequently
