Thanks. It's great to get the attaboys. Thanks again.
Here's a summary of the process.
Software:
Affinity Designer (AD)
Silhouette Studio Designer Edition (SS)
Artifex Forge Mosaic Maker
Online Studio to SVG converter
Equipment and materials:
Silhouette Cameo v3
Heat press
Heat Transfer Vinyl (HTV)
T-shirt
I imported the boat image from the internet and traced it using Silhouette Studio. Saved it as a .studio file. I used an online service to save it as an SVG file (http://www.ideas-r-us-software.uk/FileConverters/SilhouetteStudioConverter.aspx).
I cleaned up the SVG file in AD and created the border design using Artifex Mosaic Maker.
Exported the design as PNG (SVG won’t work) and traced it in SS. Resized as needed and cut the HTV on the Cameo. Printed it onto the T=shirt.
It’s a pity that AD doesn’t have a trace function, but not the end of the world.
I'll post a few more of my t-shirts later.
