# Overview

## Fabric Calculator Overview When you visit your Fabric Calculator tab, the first thing you'll see is the Fabric Calculator Overview page. This is a high level overview of your quilt and will show you a quilt thumbnail, your quilt blocks, and your fabrics used. ***

### Quilt Thumbnail The quilt thumbnail gives you a reminder of what the quilt looks like. You will also see the name of the quilt, who designed it, and the quilt dimensions. It should always be reflective of the latest iteration of your quilt. But if you find that it hasn't been updated, follow these steps to update it. {% stepper %} {% step %} Go back to the **PreQuilt application tab**. Just click on the PreQuilt tab. {% endstep %} {% step %} Click on the **Save** button on the vertical toolbar. {% endstep %} {% step %} Click on **Save & Close (Update thumbnail)** button.

{% endstep %} {% step %} Go back to **Fabric Calculator tab** and refresh the browser page. You should now see the updated thumbail image. {% endstep %} {% endstepper %} ***

### Quilt Blocks {% hint style="info" %} **TIP**: It's a good idea to name your blocks, so that they are easier to identify and organize, especially in the Fabric Calculator. {% endhint %} All the quilt blocks in your quilt will be summarized here. You will be able to note block name, the quantity of each block in the quilt, and the block's **finished** dimensions. ***

### Fabrics {% hint style="info" %} **TIP**: It's helpful to make sure your Fabric Link IDs are tidy. This will help keep your fabrics organized. Bonus tip: The shorter, the better. {% endhint %} All the fabrics being used in your quilt will be summarized here. You will be able to see your fabric's Fabric Link ID, fabric name, inches and yardage needed. **Note**: If the Fabric Link ID is used over and over, like in Fabric Link B, this is because the same fabric is used in the border as well as the quilt blocks. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
