New notions

I can call a bunch of buttons and some zippers notions, can I?
I'm learning sewing related terms in English lately. Since I haven't been sewing for more than like a year or so, I'm really just learning all terms in Dutch, my native language. But since I'm a citizen of this world, and I want to communicate, I need to learn the right words to describe certain things in English. I am always willing to learn. So if anyone catches me saying something stupid, making constant typo's, using wrong words, being confusing and all that, pls let me know! I won't be offended. but be gentle anyway... honest, but gentle.
I do know my English isn't that terrible. Maybe you would even call it fluent both verbal as well as written. But it's just not my native tongue. With every blog post there is a point of frustration because I can't find the exact words I want to use to get my message across. Ofcourse there is the beloved spellchecker and I love using it, but I not only want to know how to have something corrected for me, I want to know how to do it myself. maybe that's why there is always a paper dictionary on my desk.
