Use of "that was" in the active voice

Hi smart English people!
I’m writing a sentence in the active past tense describing a notebook. The wording is awkward.
"I treasured my mint green, pocket-sized notebook designed with silhouettes of songbirds perched on daisies."

"I treasured… notebook" is a complete thought, but the rest of the sentence seems to long and wordy of a clause. Would the sentence make more sense if I changed to "I treasured my mint green, pocket-sized notebook that was designed with silhouettes of songbirds perched on daisies."?

I want to keep writing in the active voice, so this isn’t the perfect solution. Any suggestions? Is my original sentence correct?
