Dream On Me Karley bassinet sheets? [BC]

Hello,

We recently purchased the Dream on Me Karley bassinet from Walmart to use in our bedroom for our baby boy. We read good things on Reddit and felt comfortable with the additional canopy as we have two cats. But I’m having trouble finding any sheets made specifically for this bassinet!

Does anyone have the bassinet and have any sheet recs? The dimensions listed on Walmart for the mattress are 31.5x15.5in. Would 32x16 bassinet sheets work, or would they be considered too big?

This is our first baby so we’re a combination of clueless but nervous.

Thank you!!
