Hello, I’m new to Rhino. I followed this tutorial and applied it to my surface. I managed to play with the thickness and make the diamond shapes more or less rounded.
Now I’d like to create some kind of edge/border around the whole shape. Could someone help me with that?
I tried using Pipe on the curve I used to create the surface, but it doesn’t blend nicely with the shape.

No objects in your GH file—you need to internalize geometry or provide a .3dm with your figures.
Nonetheless, it seems you used a trimmed surface as your starting brep, which means you can extract its border via BrepEdges:

here you go! I see that after adding BrepEdges, it does select the border but how to make it thicker and blend with the rest? (I’m new to Rhino). If there is another method apart from this I’m open to try it! I just like how smooth and round this one looks.
hello and thank you for this suggestion! However I find this method quite complex for a beginner and doesn’t give the effect I’m looking for.
But you’re not new to specifying 
Your problem would be solved already if you had told us from the start that you want to use MultiPipe for BOTH your surface diagrid and the border of the surface 
You’re almost there!
However, you can take some shortcuts like this:

NOTE:
The RegionIntersection component will be slow (circled in red)—if you don’t want to wait ~1 min, then I recommend using the Clipper2 plugin for FAST curve booleans, but your border curves will need to be converted to polylines.
Also, though this result is correct—a unified closed multipipe—you might still get some normal discrepancies:
Hope it helps!

Thank youuuu ! I didn’t know how to explain my problem.
About the discrepancies yeah they are a little bit annoying but I found that they are more or less that noticeable depending on the Mesh U and V.
Your new-to-rhino card will expire soon!
AND, jokes aside, I hear you, and I apologize if I appeared pedantic. My contribution was in good spirit.
In fact, I respect your learning.
The absolute path of least resistance from where you already were in your learning is like this:
Just remember, without actually trimming your grid this happens:
And so I die in peace, a bit more of what you can do for true speed coming from where you left off:

And lastly, true need-for-speed learning support material:

Thank you ! That worked perfectly. I really appreciate your help 
btw how did you learn grasshopper? Or do you have any tips?
I am still learning! I’m lightyears behind others here, believe me.
Keep asking here, and even responding when you have an answer.
Pull Curve as a trim, that’s clever.
Thanks for sharing
