good morning! you go here, in the site of my friend Lila,Cannoli e tiramisų:
http://www.ornato.it/?p=71 you will see your machine. (I have one, too), and you clic at the bottom of the page, before comments, where you see this:
Manuale Necchi BF BFL (il manuale č un a compresso, per visualizzare senza scompattare installate CDisplay)Lila is going to explain you all about vintage attachments, zigzagger and buttonholer feet, hemstitchers etc.
so you you can embroider with your bf. I bought some from Lila, and some from US ebay where you find thousands.
look at the price! I saw for 400$ the same foot I bought in Italy for 20 €, ahahah
. but there are a lot of good prices in US. here in Italy, we are a few with these kind of machines.
singer attachments are generally good for this necchi. they must be low shank saluti dall'italia
ciao
