I used straight pins until I got tired of the puncture wounds. Also didn't like the pins falling out and DH stepping on them (he wasn't happy). I switched to regular safety pins and they were OK but a little difficult to work with. Then I found the curved quilters safety pins. They are a little expensive unless you use a discount coupon and buy the larger packages, but they are well worth it. When I am basting a really large quilt I use a curved tool (button hook or similar) to help fasten the pins so my hands don't get quite as tired.
