If you make wee items, as in items about the size of a Shiatsu or smaller, I very definitely suggest making (or shelling out the cash) for a photo light box. This is essentially a square, white tent that can set you back way too much money if yer not shopping at the right places. I picked up a GREAT light box from DealXtreme. The name of the website alone is a wet dream for those frugal folk that create.

You can grab some lights, those with the adjustable goose-necks, or use natural lighting. Natural lighting is my jam. It's free (for now), and it's heaps more evenly displaced than your everyday lighting devices.
Maybe you're feeling adventurous. You can also whip up your own light box. It's not too hard, but it's not too collapsible. I followed this tutorial to get me going my first time 'round - I used parchment paper for the window bits.
Some of us don't have the steadiest of hands, now. And shooting the same thing bent over on your dirty kitchen table gets a bit drab. You begin to perspire and you just want to go home already. You realize you are home, and you become extremely judgmental of your shitty kitchen wall colour, and go a bit mad - there's too much wood paneling everywhere (or not enough). If you want to avoid these damning feels, invest $10-$20 in a mini tripod. One decent birthday (it was a B-), I received a Dynex mini tripod. Someone clearly had an $11-bill burning a hole in their pocket.

Product photography is important! A crisp white background is always nice. You don't need anything fancy - in fact, I use $0.50 poster-board from Dollarama. It's cheap, easy to replace, you can't go wrong 'ere.
Now that you have a nice little set up, you will very likely need to move onto the photo editing. I use Photoshop. I like to crop, whiten my whites, and deepen my darks. Photoshop will cost you an arm and a leg if you purchase the program in store. It sucks, bad. That's not to say there's not good (enough) free options though. Here's a few programs and sites to check out:
Check your local community events for photography workshops. Some are free, some run off your donations or will charge a small fee. I'd avoid those classes that charge ya up the arse, maybe I listen to too much Crass though.
That's about the basics for getting started on rad product shots. Though my final tip is this: be certain your actual products are well made and easy on the eyes. If your items that are handmade, vintage, or supplies aren't swell, your photos won't be swell. You wouldn't want to end up on Regretsy (RIP).
