# Siblings metafields

> Feature introduced in Pipeline 6.2

There are two product metafields definitions required to connect each of the products together and generate linked swatches.  

Using the Shopify Admin, choose **Settings** -> **Custom data** -> **Products**

Both metafields will be defined under the category of **Products**

Choose the **Add definition** button. If this is your first time creating a metafield, the options may look similar to this, simply click on one of the Add definition buttons:

Tip: If you are new to creating custom metafields, a good step-by-step walkthrough is also available in the [Cart Upselling](/upsell/upselling/cart.md) article.&#x20;
{% endhint %}

Next, create these **two** metafields:

{% content-ref url="/pages/BUBV2MPPpytt3f9uZTLB" %}
[Cutline](/siblings/product-siblings/cutline.md)
{% endcontent-ref %}

{% content-ref url="/pages/id2b2GJeU3UEQgjrtJ8E" %}
[Siblings collection](/siblings/product-siblings/siblings-collection.md)
{% endcontent-ref %}
