Hey guys,
My oldest son (17) is looking to customize my old bicycle with paint and also wants to put a custom logo on the front tube. How would someone go about doing the logo? Perhaps in a sticker form?
This is the logo he made by combining a few pictures.

You can buy label paper for your home printer that will do a pretty good job (you will need to cut it out). You will want to clear coat it before you put it on of course. I did this for some motorcycle decals that I wanted to reproduce.
You can even get decal paper (I think it only works for inkjets).
If you go with the Avery style labels, get the ones with the least amount of stickers per page (I think two is the minimum). This allows you to make bigger sticker since you will need to cut them out anyway. Doing sticker with complicated boarders (e.g. diecut style) can be a bit of work to cut out.
Teespring.com will print them for you, just upload the image. Not sure what the cost would be though.
