Definitely get a couple of inexpensive but nice looking pearls. Go look at Wen on Etsy. Find something that you think you'd wear..maybe some ripple pearls ? You don't want to completely waste your money on rubbish and then toss them. May as well practice on something inexpensive but fun...that you would actually wear.. If by chance then you find you are Not Interested in knotting..you can always take them and use little bumper silicon beads on some fine Soft Flex wire , string em up, stick a clasp on and crimp them shut. necklace !
