Make, learn and talk about needle lace.
As to making stitches correctly -- there are many, many variants of buttonhole stitch which are used in needle lace. One night I went through all my books and made a little sketch of each stitch and its variants. I ended up with 10 pages of tiny penciled diagrams. So if your method of making a stitch is not correct for one style of lace, it probably will be correct for another. Also many of us are designing our own modern work. I do that because I just can't work on the fine traditional scale -- I just can't see it -- and because I can used whatever stitches I want wherever I want. Absolute freedom!!!
We have a group for discussions of stitches and their variants --
We also have an album of photos of stitches, close up.
On my personal website I have a page of diagrams of what I think are the most basic commonly used stitches.
