And here is a "recipe" for a type of ornament I use a lot on my tree: Bead icicles.

Backstory:
When I was a kid, my parents caught our then-cat, Sam, pulling tinsel off the tree and eating it. That was the end of tinsel in the household (and very luckily, not the end of Sam; many cats and dogs die from intestinal blockages from similar ingested items).

So, we substituted glass icicle ornaments. And then, sometime in the mid 90s, I found a description of icicles you could make - it was one of those "holiday craft" publications, perhaps put out by Better Homes and Gardens. The original had you thread the beads and buttons on thread, which you then had to tie off - a real pain and non-permanent. I've made variants on these over the years, but I think my 2003 version is the best.

There are two fun parts to this: buying the supplies and making the icicles.

What you will need:

Beading wire (I used 32 gauge; don't go much heavier than that)

"drop" beads (beads with a hole near the top, similar to the glass drops that used to be on chandeliers.) These are not absolutely necessary but they are nice

An assortment of glass, crystal, semiprecious stone, and/or plastic beads. You can also use antique glass buttons; some of the icicles I made some years ago for my mom included glass buttons from her mother's button box.

Jewelry "crimp bead" findings (or whatever they are called. I didn't use them but I think they would be a nice addition at the end)

Fun part #1:Go bead-hunting.

Hit your local crafts-purveyor(s). If you are lucky, they will have nice beads. I personally think the glass/crystal beads look classier, but if you need to make a lot of these inexpensively, or if you are working with children, the plastic beads are fine too. Also, the plastic beads come in spoked-wheel shapes and chandelier-drop shapes and the like that are hard to find in glass beads, or that would be too heavy.

A couple of considerations:
Get a good size range. You want to be able to graduate the beads from small to large as you go up the icicle. Also get a good range of shapes, all round beads on an icicle look sort of funny. Faceted beads are good as they catch the light.

Don't pick huge glass beads, they will be too heavy.

Silver beading wire seems to be the least conspicuous. You can also use fishing line, but it's more of a pain to work with, and you have to tie it off somehow.

Get a variety of colors - mostly clear, but some frosted or white or crackled-clear beads. You can also include a few pastel colored beads, either clear or opaque (I'm partial to icicles with a few clear pale-blue or clear pale-pink beads inserted for color).

Try the antique shops, too. Or your grandma's button box, if you were lucky enough to inherit it.

Look on the button aisle for glass or glass-like buttons, they work too.

The Swarovski crystal beads sold for necklace making are a bit pricey but really add a nice touch to the icicles.

Fun part 2: Make the icicles.

Cut a length of wire about three times as long as you want your icicle to be. Thread the drop bead or the bottom most bead of your icicle onto the wire. Now, "fold" the wire - so you have both lengths of it running parallel. You will be threading both lengths through the successive beads (or through two holes on the buttons). This holds your icicle together.

Take more beads and thread them on the wire. Try for a general small-to-larger progression. Also try to insert a few frosted-glass or colored beads here and there for more interest. (random looks better than matchie-poo on these). Keep adding beads until it is long enough (don't go all the way to the end of the wire).

Then, take the remaining wire and wrap it around your finger to form a loop, and twist the end around itself at the top of the icicle. This is where, if you have those crimpy things that people use to hold bead-wire or cord on necklaces, you can crimp one of those on the top of your icicle and hold the wire ends in place. Cut off any loose wire ends.

Hang on your Christmas tree, or from hooks on your mantel, or from the arms of your chandelier, and enjoy...

I don't consider that I hold the copyright on this idea - as I said, I think one of the crafts-staffers at BH&G came up with it - but I think my changes and way of describing it is different enough that I'm not violating anything by posting it here. (As for making these and selling them, I'm not sure of the legality on that).
