My sewing machine is a Bernina-Aurora 430. It's the machine I used during college and when they sold the used ones for a discount price, I snagged one for myself. I use this baby at least an hour a day if not more, and it has never given me any problems. There are some quilting features on it that I don't use, but I have loved this faithful machine. I'm pretty sure I can use this one my whole life and probably pass it down to my kids.
My serger is a Brother 1034D. It was a surprise from my husband, and it has been completely amazing. I really don't know how I sewed without a serger. It's user friendly, and it can do lots of different things.
I use a Nikon D3100. I don't know much about DSLR or photography, so I learn something new every time I use it.
Two things you can't live without:
-I always wear scissors on a ribbon around my neck. Many times I find the scissors hanging around my neck after I've been walking around a store or when I answer the door.
-Tailor's Chalk. A lifesaver! This stuff shows up on everything and disappears with just a little bit of steam. I use it on virtually every project I do.
