Put a round 2-3 mm silver or gold bead on each side of the hole and wrap your wire down to the bead.
Or I use a 4 mm clear swarovsky crystal bicone on each side [or just on one side if you want] and put a big seed bead or a small round glass bead on the other side-or a small round pearl-or gemstone 4mm or smaller..

When I'm stringing beads with large holes (weather on wire string or pins), I'll string a tiny bead first, then place the larger bead over-top (so that the tiny bead is actually 'inside' the hole of the larger bead). You cannot see the tiny bead underneath, and it keeps the larger bead from moving around. I've used mostly crimp beads and seed beads for this. You could try a clear, crystal seed bead, so it is transparent.

I use a clear sead bead of the width I want (I have an assortment) and put it inside the larger bead,

Lisy, I like to use the clear rubber stoppers for the backs of earrings. They fit perfectly into the holes of the large lampwork beads and any large bead. sometimes I also use the smaller white rubber stopper and just cut it to size. It will keep the bead straight on the headpin or wire. Clear "Rubber" Earwire Clutch

Lisey, whether your headpin has a flat head or a ball, you need to use a heishi spacer or a bead cap with a hole small enough that the head of the headpin will not go through and big enough in circumference to cover the hole of the lampwork bead. For interest,. bead caps are nice addition on the top hole of the bead to frame your bead. Another way to make your earrings interesting is to flip a bead cap around away from the bead and place a lovely crystal or pearl accent bead that compliments the colors in your lampwork inside the cup of the inverted bead cap making a little flower like shape.. The correct size bead cap or heishi should cover the holes of your lampwork beads. Any variations of the above will work. With your two uniquely handmade beads and all the beautifully scrolled beadcaps, interesting heishi spacers, gem stones, pearls, new cool shapes and awesome colors in Swarovski crystal available in todays market, you should have no trouble finding the right combination and accent beads to make your lampwork beads pop. Good luck creating your earrings that will be uniquely yours and you will love to wear. Happy beading Lisey!!

There are "donut hole bails." You can gently squeeze them around the material. They come together at the top where there are 2 holes which line-up (use as one) for stringing. There are also "Ice pick" bails, which work like an...you guessed it, an ice pick. It has 2 pincers, one in the fron, one in the back. They squeeze together into the pendant hole and have a bail at the top. Watch WHICH WAY the ice pick grabs: side to side or front to back.

You can always wire wrap the donut or flat pendant or you can use a bail.

Not unless you plan on licking it or holding it excessively and then eating something with your fingers, the lead content is usually very slight. So it shouldn't be a problem.

It depends. If you are going to wear it for a long period of time and not take it off, then I wouldn't worry. If you are going to be active and you might end up taking it off then I would suggest you be cautious where you put it, especially if there are little kids around that are looking for something to suck on.

SEED BEADS.

No, I think they are way too big.

At Artbeads.com, in our Learning Center, we actually have a chart called TOHO™ Color Warnings. This chart lists the colors that may be changed by bleach or oxidation, colors that may rub off with strong friction and colors that may fade with direct sunlight(UV's). Here is a link to that chart so you are able to view it easier:

Use real metal. I have been using seed beads for 10 years and I have never had a problem with any losing their shine. Since you are having this problem, use real metal... silver, hematite, gold, etc. They are expensive, but will maintain their finish.

Most of the ear threads on this site have a ring at the end of them that you can hang beads or charms from.
This site also has jewelry desighns that use ear threads in the learning center if you need inspiration

Swarovski beads are lead crystal, which gives them the same clarity and radiance as is the difference between lead crystal stemware and plain glass.

Additionally, Swarovski crystals are cut, whereas most glass beads are pressed or blown into shape.

SIZE 10 OR 11 SEED BEEDS. MIYUKI ARE BEST. U CAN WEAVE 4MM BICONE SWAROVSKI CRYSTALS! IF GLASS BEADS, USE 4 MM

You can use a lot of beads, but seed beads would work nicely. There are a lot of sizes, colors and finishes.

I wouldn't use a jump ring at all. They come open. I would use a split ring maybe 7mm in diameter. Not sterling silver because when you bend it open it will lose some of it's shape. A split ring will only come open again if you WANT it to.
