I have searched both Squarespace and Cloudflare Support as well as blogs. I don't have any specific instructions on the best way to utilize the Free version of the Cloudflare CDN with Squarespace. If its even possible. I get a notification of SSL on the site.
Squarespace Support gave me this link:
If you can't do it on the Free plan, whats the best method on the Cloudflare premium plan? Change to the Cloudflare Name servers?

Point your nameservers at CloudFlare
Set up the www domain, as instructed
Send the @ name back to your domain provider’s default IP address. I use Hover, so that address is 184.108.40.206.
At your domain host, forward the domain as though you had never pointed your DNS at CloudFlare.
You’re basically sending the nameserver to CloudFlare then bouncing the non-www record back to the original host, who still has your DNS setup even though it’s inactive. Your host then forwards the domain on to the correct destination.
You could almost certainly make this work with CloudFlare’s new Page Rules / Forwarding system as well but I haven’t tested it yet.

As an update:
The free plan of CloudFlare now support SSL.
Instead of pointing back to the original DNS host, use rules in CloudFlare.
Squarespace already have their own CDN for static contents therefore use CloudFlare for DDOS, hotlinking and traffic protection and management.
Everything is working fine for me, but it would be really great to have some input from the Squarespace team in terms of best practices.
