earrings

[stasiia.livejournal.com]

i looked in the memories section..but i have more questions about making earrings..
what are good stores besides michaels, to find beads/stuff for making earrings. it seems a lot of websites sell pieces for expensive?

are there any tutorials that are easy to understand?

are we allowed to posts pics of something we make and ask how much people would pay to buy it?

how would i go about making earrlings similiar to these?

i have been using headpins..and these seem like the balls are just attatched to string?..glued in? something else?
