), but it also crowned a 15th winner of the reality design series.

Here she talks to EW about the ups and downs of season 15.
ENTERTAINMENT WEEKLY: Congratulations!
How does it feel?ERIN ROBERTSON:I dont understand feelings anymore after this.
Every day I think about everything thats happened and its just been something new in my brain.
Oh, my god.
I actually dont even know.
Yeah, maybe thats my answer.
Its just a bunch of jumbled up words.
So we didnt have a day off until after the seventh challenge.
Everyone was just completely out of it.
I think I was just emotionally and physically tired.
A lot of fans have appreciated how there was such great camaraderie this season among the designers.
Did it feel that way from the designers perspectives as well?Yeah, definitely.
Genuinely, everyone was really good.
Dexter and I were never rude to Cornelius at all.
Actually, we got along really well.
Our whole time working, we were laughing with Cornelius.
On his own, hes just a worry worm.
Who did you think was your biggest threat throughout the season?People ask me that all the time.
I think threat seems so aggressive.
I was like, Anyone can win!
No one really was, and no one really had anyone elses aesthetic.
We were all very much individuals in that way.
I was expecting black leather jacket, like badass.
And then I saw it, and was like, Oh my gosh she went so sweet and soft.
I was like, You gave us all a surprise.
When Tim came 10 days before NYFW, you didnt have any garments completed.
So its not like I was, Im not going to have this done.
Just from being on this show, I learned to make an outfit in a day.
Also, I have to know: How were you not bothered by handling mealworms!
?I dont know!
I was just like, this is going to be great TV!
The whole crew was super excited to have this daylight to blacklight.
The energy in the room was special.
It felt like we were kids like, Oh my god.
How does this react?
What does this do?
It was really fun.
And I also really liked Laurences cocktail challenge dress with the Chesterfield sleeve.
I didnt get to put sleeves on it because I didnt have time.
Your mom seemed to likeit, though?My moms so cute.
Shes like, Ill like anything that you like.
I was like, Mom, help me out!
But when its so open, its hard to decide where to go.
So whats next for you?Im in the process of figuring out exactly what Im doing.
I want to work on commissions and one-of-a-kind pieces of clothing.
I really like fashion as art and making something for someone thats completely special and unique to them.
