I used one of hubby's guitar picks as a template to get the size & shape right. I saw some different shapes online. I even saw a heart shaped one. The larger end isn't as important as the end that goes on the strings. It needs to come to a point & be really thin. The indentions help make it easier to grip, since the glass is so smooth & slick.
1) Make a blob on the end of my rod.
2) Shape the blob in to a pear shape & flattened it.
3) Make the ribbed indentions to help grip it.
4) Punty it up on a boro rod with the ibiger end/ndention part attached to the boro.
5) Heat the section attached to original rod & pull it out.
6) Then, flatten the point & smooth the whole thing out.
Here are a few more I made. Sorry for the bad picture. I'm just using my phone. I promise they look much better in person. The red/yellow one is a little wonky on one side though LOL.
