This Barbie dress was made from a simple acrylic yarn and light pink netting. I just used some of the leftover netting I had from another project. You also could go to Joann's or any store that sells remnants and see if you can find something cheap there.
I knit this dress on my old Barbie Knitting machine but you can also use double pointed needles or circular needles. Just make sure you check your gauge before starting to project.
Gauge: 2 in sq= 12 rows and 7 stitches
To make the veil I took a smaller crochet hook I believe I used size H. Then I just chained a few stitched together and hand sewed on some netting.
