How can I customize a free Blogspot shop template to align with my brand's visual identity?

You can customize a free Blogspot shop template primarily through the 'Theme' section of your Blogspot dashboard. Use the 'Customize' option to change colors, fonts, background images, and add your logo without coding. For deeper customization like modifying specific sections or adding custom widgets, you might need to edit the HTML/XML code directly, which requires basic understanding of web development.
