all of the above! tho i found a fantastic book on sewing which helps with all of the basics plus extras. it goes on about what you should have in your sewing box plus what each sewing foot is for and how to sew different fabrics and what stitch to use for what. its a fantastic book. cost about $60 i think from memory. feel free to pm me if you want the name of it

sewing is very addictive and trust me you wont want to just do baby clothes! good luck and let us know how you get on
