If you're getting someone to draw, get them to use a fine tip felt rather than a ball point pen.
Avoid things that are not saturated, like crayons or pencils.
TIP: Use this template HERE. Crop print it out as big as you'd like and get your loved one to write inside it! It doesn't matter what size you make it - I can resize it to fit the piece you pick!
HERE is a guide on how to pick something to fit an engraved bar.
Not sure if your image will work?Contact me and I can double check for you and provide suggestions. We also provide custom design services; for example, piecing words from a card together to create a custom piece!
