if you decide to pin baste instead you will need basting pins. I like Dritz curved basting pins in the 1.5" length. I prefer them in the Dritz brand because they go through the fabric easier. Some quilters may use the 1" size but I prefer the longer ones. If you baste with pins make they go all the way through the quilt sandwich and grip a piece of the backing. https://www.amazon.com/Dritz-3031-Basting-Nickel-Plated-75-Count/dp/B001UAF6FI?ref_=ast_bl_cpl_dp&th=1
