No, you do not have enough Pellon
The addition for your measurements is:
18.5+5+4.5+9 = 37 inches
Then,
13.5+7+9 = 29.5
The 5"XWOF is the ?? factor for me.
I have Fusible#805 Pellon that is 17" wide. And, I have the Pellon Decor Bond that is 44" wide.
So it depends on what type of Pellon that you need for your tote.
Sorry to be the bearor of bad news, but you do need more Pellon to finish your tote.
Good Luck,
Susan
