What were the notions you used most at your aunt's? Why not start there. My suggestion would be a rotary cutter, the largest mat you can afford, 12 x 6 ruler, seam ripper, small thread scissors (I very seldom use my large ones) and several spools of thread in neutral colors. Also extra needles for your sewing machine and maybe some hand sewing needles and a thimble. Almost forgot the pins. I like long, thin ones.
