ISO pillow recovering

We’re looking for someone who can recover these 4 small loose cushions for my friend — 2 tie-on chair bottoms and 2 slip-on chair backs (integral pocket enables slip-on) — and advise how much fabric to buy once chair measurements are provided. I realize the yardage will vary depending on whether the print requires some type of pattern matching. It hasn’t been picked out yet. There are only 2 bar stools, so 4 cushions total. See photo. Thanks.
