Best christmas gift for sister

I’m looking for gift ideas for my boyfriend’s brother and his fiance They’re both 25 We plan to spend about 100 total which is flexible for a good gift We might give them each one or two gifts I’ll tell them a little about themselves they love nature, but don’t do much besides gardening their honeymoon will probably be in Colorado He drinks coffee occasionally she doesn’t drink at all She’s a teacher he’s an accountant They just bought a house this year and are very busy They’re getting married next year We’ve given alcoholic beverages before like cocktail shakers, etc, so I’d rather avoid it

It sounds strange, but I bought a dualhead shower head for my boyfriend, who’s a teacher I’m an accountant and would love to have one too

If you have to do any housework, you could get a tool or a DIY item eg, an air purifier Maybe something to give the house a more “homey” feel eg, a Bluetooth picture frame, a shower speaker, matching succulent pots

A fireplace for your garden
