since I'm learning how to critique, I hope you will consider this as a positive attempt in that direction

1. The title Picnic basket is great also revealing what to expect...i liked that as an element of surprise
2. I find repetition of words in few verses which if you want can be easily fixed...here is a suuggestion:-

Like a jar of peanut butter
And a jar of jelly

Like a jar of peanut butter
and a can of jelly
....................................
And make something Sticky
To make something Grand

And make something Sticky
beyond the picnic time
........................................................
I did not understand why you chose to capitalize first alphabets of every line

thanks for reading
