Scented soap may not seem like the very height of gift-giving originality, but it’s really nice to have a stack on hand as a hostess present or to give out to the ladies when you’re on the hook for a crowd. And the fragrances from the Red Hook soap and flower shop Saipua are just delish: beautifully packaged, bright, fresh, vibrant, yum. The $10 bars come in Lavender Oatmeal, Peppermint Pumice, Winter Citrus, Salt Water, Mango Butter, Coffee Mint and more. Saipua is open today until 6 and tomorrow from 10 a.m. to noon at 147 Van Dyke St., conveniently located for that last-minute Fairway Run. The squares are also on sale for $12 at A. Cheng at 152 Fifth Ave. in Park Slope, which is open until at least 5 on Christmas Eve.
