## Questions & Answers

**Q: What's a good glue to secure these onto plastic or metal? Super glue isn't working well enough.**
A: I sometimes use E6000 glue.  It's not a instant bond glue, but it's very strong.  I recommend small tubes of the glue so you don't have to worry about it drying out in the tube.  I also like to roughen up the back of the pin pads with some sandpaper for extra grip.

**Q: Will these work for needle felt brooches?  I'm thinking they would make the brooch easier to attach to clothing.   Standard brooch pins can be tricky**
A: Assuming a felt backer, i would say Yes, if poked thru the backer and secured prior to the backer being affixed to the Brooch. 

with this in mind, a tack pin with a larger, maybe 10mm head, and a longer shank might work better.
These Tack shanks have a 4.5mm head on a 8mm long shank.
something with a 10mm head on a 8-10mm shank might work better, as most felt is 2-3mm thick.
this is dependent on the backer material you use of course...

**Q: Do these tacks leave holes in the fabric once they're removed? Tack pins I have used before have damaged the fabric.**
A: I believe it depends on the fabric. I used a satin/polyester blend and it did leave holes in my material.

**Q: Does B-7000 glue work well with these pin backs?**
A: yes ,it can be work well.
