I can answer because I just did this for a client.

I went in and edited the page template and just moved the description text block code lower in the page.

On the template I was working on it was around line 100 of the “collections-template.liquid” file

Immediately below the:

<h1 class=”SectionHeader\_\_Heading Heading u-h1″>{{ collection.title }}</h1>

is the description field:

<div style=”padding-left: 4%; padding-right: 4%; font-size: 14px;>

{%- if collection.description != blank -%}

<div class=””>

{{- collection.description -}}

</div>

{%- endif -%}

which I moved to about line 400, below the “collection_toolbar “
