Here's what I did:
I already had the pillow and asked my mom's friend who had a sewing machine to create a simple pillowcase with the dollar or two worth of fabric I purchased at JoAnns (I like this muted auburn color better than the bright orange shown in the orig tutorial). I searched everywhere for just the right width and colored tape. Finally found it at Home Depot--electrical wiring tape comes in all colors (and for cheap...a huge role for about $3, of which I used only a tiny fraction)!
Taped from top to bottom, left to right to create chevrons.
Starting to look like a salmon fillet, right? Wool "seaweed" belt with both velcro and clasps attached (again, I don't sew so I had mom complete this for me :). Original tutorial said to use a wide green ribbon, but I thought black looked more realistic and that wool would be more sturdy. I'm glad I did so since Audrey tried to yank off the belt with all her might.
Ta-da! Salmon sushi roll on a bed of rice (my blanket throw I got from Marshalls)
My Audrey salmon roll is too cute to eat :). I got her a white shirt and leggings at H&M for around $10. Both items can be re-worn as normal clothes.
One salmon roll coming right up for Auntie Steph. But quick before she squirms away!
Waiting in line for the free pony ride for 30+ min sure was tiring for Audrey.
But so worth the wait. She loved every second of her ride and couldn't stop talking about it on the car ride home.
