Yarn Dye Lot Tracker

Why Color Matching Matters

When hand-dyed or variegated yarns change dye lots between purchases, the color differences can create unwanted stripes or banding in your finished project. This is especially true for shawls, scarves, and garments where color flows continuously. Buying extra yarn is expensive, and many specialty yarns are discontinued without clear substitutes.

This tracker helps you avoid those problems by planning colors before you start. Enter your yarn details once, and the system shows which dye lots will match and which colors will blend smoothly. When your favorite yarn is discontinued, use the substitution panel to find alternatives that work with your project.

Getting Started

1. Enter your yarn details - Fiber content, dye lot, and color name. Use the preset buttons to load common hand-dyed yarns.
2. Check the matches - The system shows similar dye lots with confidence percentages. Higher numbers mean better matches.
3. Plan gradients - Enter start and end colors to see smooth transition steps. Copy the steps to your pattern notes.
4. Find substitutes - When a yarn is discontinued, enter what you have and what you need. The calculator suggests viable alternatives.

Common Mistakes to Avoid

• Not checking dye lot numbers when buying yarn for a project in progress
• Assuming all blues are similar - navy, sky, and teal can be very different
• Ignoring fiber content when substituting - wool and cotton behave differently
• Relying on screen colors without testing under your actual lighting conditions

Color Family Guide

The color family selector helps group similar hues. Blue includes navy, sky, and teal. Green covers forest, mint, and olive. Neutral covers grays, beiges, and off-whites that work as transitions. Use this when planning gradients or substitutions.

Working with Gradients

Smooth color transitions need careful planning. The gradient calculator shows intermediate colors between your start and end points. For the best results, choose yarns from the same fiber family - wool to wool, cotton to cotton. Different fibers can create unexpected texture changes even when colors match.

Step by step: Enter your starting color in the From field and your ending color in the To field. Set the number of steps based on your project length - 5 steps works for most scarves. The preview bar shows the color transition, and the step labels give you the intermediate yarn names to look for.

Pro tip: If you cant find yarn that matches an intermediate step, consider using a neutral (gray or beige) as a transition color. This creates a softer blend than forcing a bad color match.

Substitution Strategy

When searching for discontinued yarn substitutes, start with fiber content. A 100% wool substitute will behave more like your original than a wool-acrylic blend. Next, compare color families. Finally, check the dye lot numbers - newer lots often match older ones better than expected.

Stash Organization

Keep track of your yarn stash by noting dye lot numbers and color names. This tracker can help you identify which yarns work together for future projects. The history feature saves your past searches so you can quickly find matches for similar projects.
