I made this as a Valentines gift for my hubby. On the bracelet I have engraved the image of the soundwave of my voice and a QR code so hubby can hear it.
First record your message using your phone voice recorder. Take a screenshot of the soundwave.
Once recorded your message upload the voice recording to a media cloud like Dropbox or Google drive. Once you have done that copy the URL address and input into a QR code generator.
Aluminium blanks that I used for this project were purchased from: https://www.amazon.com/dp/B0CSDHKXK8?ref=ppx_yo2ov_dt_b_fed_asin_title
Replace original images in design file with your own. Then group together and size accordingly to fit you engraving blank.
Engrave onto blank using the above settings.
Once completed add jewelry band of your choosing. I used a macrame design with leather cord.
