The ideas here range from a single serape runner on the dessert table to a full marigold arch at the door, and the cost and effort scale with how much space you fill.
With a week or more, cut tissue papel picado or build a piñata from scratch; with only a few days, buy ready-made banners and chili ristras and put that time into arranging one or two focal spots instead.
1. Sombreros
Sombreros double as wall decor and photo props, so guests can wear them during the party and you get twice the use from the same budget.
Set one on the gift table or the dessert table, then hand a few to guests at the door so they double as photo accessories.
Buy a couple of dressy ones for display and keep the rest cheap, since guests will toss them on and off all night.
For me the fabric roses are the detail worth copying: they tie the hat to the rest of your flowers.
2. Serapes
Striped serape runners do the work of a tablecloth and a color palette at once. Lay one down the length of a dessert table, and the stripes hide spills and crumbs better than a plain white cloth would.
Pick a single runner and let the balloons and banners borrow its colors, because several competing stripes get busy fast. A runner costs less than rented linens, and you can reuse it as a throw on a porch chair afterward.
3. Papel Picado
Hung in a line, papel picado banners turn a bare wall or a spot over a backdrop into a finished scene.
The pink and white pairing shows you are not stuck with the classic rainbow; match the paper to your party colors and it reads as a deliberate choice.
Buy a ready-made string if time is short.
To DIY, fold tissue paper in layers and snip shapes, then tape the panels to twine. Hang them where there is no strong wind.
4. Cacti and Succulents
Cacti and succulents in terracotta pots give a table living greenery that needs no watering on party day. Group several sizes together on the table, and let the pots hold the color rather than adding more fabric.
Small plants from a garden center are cheap, and guests can take them home as favors.
Faux ones work if the party is weeks away, but real plants look better up close. Keep spiny cacti away from the edges of the table.
5. Clay or Ceramic Pots
Terracotta pots with carved floral patterns bring an earthy, handmade look that plastic serveware cannot match. Line them up on a shelf or sideboard as display, or use them to hold salsa, chips or utensils.
If you plan to serve food in them, line each pot with a bowl or parchment first.
Check that any unglazed clay is clean and dry. Mix sizes for height, and a single row already looks intentional.
6. Chili Pepper Decorations
Dried red chili peppers strung into bunches add a rustic note that costs very little. Hang them from a pergola, porch beam or doorway, where their deep red stands out against wood.
Buy ready-made ristras if you want a quick job; stringing your own takes patience and drying time.
I would hang them with flowers, as the pergola does, to soften the heat of all that red. Keep them out of reach of curious kids, since the dried peppers can irritate skin and eyes.
7. Mini Maracas
Mini maracas shake like party favors and sit like table decor, so one purchase covers both jobs.
Paint or wrap them in your party colors, and a plain brown one next to bright ones keeps the group from looking too busy.
Set a few in a basket by the door and let guests grab one. Buy a pack if time is short; decorating blank ones takes a free afternoon and a few markers.
8. Mexican Food Picks
Small flag picks turn a layered red, white and green cup into a dish that matches the party. Spoon the layers in separate bands so the colors stay clean, then press a pick into the top of each bowl.
Serving single portions saves guests from crowding one big dish.
I would set them on a green tablecloth beside fruit, as the photo does, so the 3 colors stand out. Picks are cheap and come in packs, so buy a few extra.
9. Margarita Glasses
Margarita glasses with a colored rim make the drink part of the decor.
Stand them on a mirrored tray or a bright cloth so the glass catches light.
Wash and dry them before guests arrive, since smudges show on clear glass. Mismatched sets are fine if the shapes are close.
10. Mexican Centerpieces
Serape placemats, clay pottery and low flowers give a long table its theme without a single banner. Red napkins and red glassware repeat one color down the whole length, and I like that restraint.
Keep the flowers low enough that guests can talk across them.
Use clay pots as vases, and add a few matching blooms at each place if you want a fuller look. Build the table around one runner or set of placemats so the rest can stay simple.
11. Marigold Floral Arch
A doorway packed with orange marigolds and purple flowers works as both entrance and photo spot. Small straw hats and woven baskets tucked into the blooms add texture and tie back to the sombrero decor.
Choose a wooden frame or porch opening you already have, since the flowers do the covering.
Fresh blooms look best, but faux garlands wired on ahead save time on party day. I would stick to orange and one contrast color so it reads as a deliberate design.
12. Traditional Piñatas
A star piñata fringed in rainbow tissue paper looks like decor long before anyone swings at it. Hang it from the ceiling early, and let the streamers trail so it fills the empty space overhead.
Buy one ready-made for speed.
To DIY, layer strips of fringed tissue on a paper form, working from the bottom up so each row overlaps the last. Hang it where there is clear space around it, and keep breakables away from the swing zone.
13. Welcome to Mexico Banner
Brown kraft paper gives a welcome banner a rustic base that suits cactus drawings and a taco doodle better than glossy printed vinyl would.
Lay it across a table front or hang it over the food, and the hand-lettered "Welcome to MEXICO" tells guests the theme before they reach the chips.
To DIY, cut a long strip of brown paper, letter the words in thick marker, and add cacti and a taco around them. Small papel picado cutouts glued along the edge bring in color without crowding the lettering.
I would keep the lettering to one dark color so the cutouts carry the brights. Draw it the night before so you are not sketching at party time.
Tips for Decorating
Choose a pair of focal spots, say the food table and the front door, and let the rest of the room stay simple.
A few grouped spots look fuller than decorations spread thin, and they give guests an obvious place to take photos.
The food table is the best first choice. A tablecloth made from layered, overlapping serapes sets the look fast; add a few sombreros around the room and put the food in clay or ceramic pots.
The dessert table is the second. Tissue paper flowers can hang from a chandelier or light fixture above it; add mesh ribbon for fullness.
Green, white and red are the colors of the Mexican flag, so a pennant banner in those shades strung across a wall reads as on theme at once. Hang it near the food, where guests will gather.
Food and Drink Recommendations
Build the menu around tacos and enchiladas, then let the drinks do the rest of the theming.
A classic margarita is just tequila, triple sec and fresh lime juice. Blend them with ice or pour them over it, and add 1 fruit flavor like strawberry or pineapple for guests who want something sweeter.
Skip the classic wide, low glass for guests who will be walking around. It spills easily, and a jelly jar works just as well.
If the guest list runs large, a local party supply store will usually rent out a frozen margarita machine. Add a Paloma or a Tequila Sunrise for variety.
Keep cerveza on hand for guests who avoid tequila. For beer, I stock Modelo, Corona, Pacifico, Tecate and Dos Equis, since guests tend to reach for those first.

Papel picado is the best-known one: strings of cut tissue paper banners hung in a line across a wall or over a backdrop. Piñatas, serape runners, and ristras (strung dried red chili peppers) round out the classic set.
