This video tutorial by Karen Baskett DIYer demonstrates how to create a Coffee & Donuts-themed split vinyl tumbler. Below is a summary of the key steps for your blog:

Process Overview:

• Preparation: After sanding the tumbler, the creator uses two different vinyl patterns (Coffee and Donuts from Donkey Craft Vinyl) 
• Vinyl Application: A clever tip shared is using glass cleaner to spritz the tumbler surface before applying vinyl, which allows for easy repositioning .
• Creating the Center Strip: The creator masks off a section in the middle to paint it with Pink Pizazz and apply matching pink glitter. A second coat is applied using Glitter Glue to ensure full coverage and crisp lines
• Finishing Touches: After dusting off excess glitter, a decorative washi tape is applied over the seams, followed by a vinyl quote "Better Together" 
• Sealing: The project is completed with multiple layers of Brite Tone, allowing 4 hours of drying time between each coat for a professional finish.

This project is highly customizable, allowing crafters to mix and match various vinyl patterns and glitter colors.
