The home gifts under $50 I'd actually give are the small pieces that change how a room feels: tree-shaped tapers, a wood bead garland, a marble box on a console. Everything here was under $50 on the retailer's page when I checked, and prices change, so look before you buy.
Candles and light
Light is the easiest way to make a home gift feel like more than the price. Tree-shaped tapers on a table and a string of warm lights on a shelf do a lot of work without extra decor. For more Christmas pieces to wrap, see my Christmas decor gift guide.
Creative Co-Op Tree Shaped Taper Candles

These unscented tree-shaped tapers come as a boxed set of two in eggnog beige. I'd put them on a dining table or a mantel where the silhouette can sit out even before they're lit. They read like a small sculpture, which is what I want from a home gift that still feels considered.
Amazon
Creative Co-Op Tree Shaped Taper Candles $17.99
A boxed pair I'd wrap for anyone who likes a simple table setting.
ZAIYW Battery Operated String Lights

This is a four-pack of battery-operated warm white string lights, each 16.5 feet with a remote. I'd tuck a strand into a bowl, along a shelf or around a stack of books when I want a little glow without hunting for an outlet.
Amazon
ZAIYW Battery Operated String Lights $21.99
Warm white lights I'd use where a plug isn't handy.
Home gifts under $50 I'd put on the mantel
I'd keep a mantel simple: a wood bead garland and a set of stocking holders. "Such an easy way to make a statement without adding a ton of Christmas decorations!"
AceList 72-Inch Wood Bead Garland

This 72-inch garland is natural wood beads with jute tassels at the ends. I'd drape it along a mantel, on a console or over a stack of books when I want texture without a lot of extra Christmas pieces.
Amazon
AceList 72-Inch Wood Bead Garland $13.99
Natural wood beads I'd layer on a mantel or a bookshelf.
Landhoow Stocking Holders

This is a set of six black mantel stocking holders. I'd use them on a fireplace mantel so the stockings hang in a straight line, and they stay useful after you take the greenery down.
Amazon
Landhoow Stocking Holders $39.99
A set of black mantel hooks I'd use to hang stockings in a neat row.
Small display gifts
A marble box and a picture light are the kind of gifts that stay out after the holidays. I'd wrap either one for someone who likes a collected console or a favorite print on the wall.
5-Inch Round Marble Box in Natural

This 5-inch round marble box in Natural is Threshold designed with Studio McGee. I'd put it on a coffee table or a nightstand as a small lidded box that still looks finished after the holidays.
Target
5-Inch Round Marble Box in Natural $22.00
A small marble box I'd wrap as a display gift for a console or nightstand.
HOWMZON Wireless Picture Light

This 16-inch wireless picture light runs on a battery and comes with a remote. I'd set it over a favorite frame or a mirror when I want that finished gallery look without hardwiring.
Amazon
HOWMZON Wireless Picture Light $35.00
A battery picture light I'd use over a frame or a mirror.
