i just want to do little pictures and personalise things, mostly for my own children and make things for them (nappies,clothes etc) but "embroidery feature" is all the information it gives on the description
though some machines will do something slightly less bolded zig zag, but they wont really do the sort of thing you seem to be talking about - for that you with need one of those computerised embroidery machines & the are expensive - I've been lusting after one for years, but even for me they aren't really worth the money as the embroidered area they cover is pretty small.
you might want to google free style machine embroidery though, you can do a lot with a very basic old zig zag/straight stitch machine & you will be able to pick a recon one of those up very cheaply
I've got a Brother machine that has an Embroidery feature but all it can really do is slightly fancier zig-zags, a sort of scalloped effect and a kind of cross-stitch. It munches up thread like nobody's business and doesn't look as nice as hand-embroidery.
Some years ago I had a go on one that could be programmed to embroider names, initials etc, but I wasn't impressed. It sort of dragged the thread across the fabric from one letter to the next in a very visible and unsightly manner. They may have improved since then but on the whole my experience of machine embroidery has been disappointing.
