DIY Wedding Planning Timeline: What to Do When, Month by Month, Including Every Craft Project

A good DIY wedding planning timeline books the big things (date, venue, food, photographer) 9 to 12 months out, makes everything that keeps (favors, signs, runners, faux flowers) between 6 and 2 months out, and saves only fresh flowers for the final week. Spread out like that, the full decor for 100 guests takes about 20 hours, which is a handful of relaxed weekends rather than one panicked one.

US couples are engaged for about 15 months on average (The Knot), so the timeline below starts at 12 months. If you have less time, do not worry. Start at whatever row matches your date and squeeze the rows above it together. Plenty of lovely weddings are planned in six months.

12 months or more: the big decisions

Everything else hangs on three choices, so make them first and in this order.

1. Budget. Agree on a total you can pay without debt and keep 10 percent aside for surprises. Our wedding budget breakdown has a simple split you can copy.
2. Guest list. A rough count within 10 people. It drives the venue size, the food bill and how many favors you make. For a sense of scale, US weddings with under 50 guests averaged $15,000 in 2024, against $42,000 for weddings with more than 100 guests (FOX 5 / The Knot).
3. Date and venue. Fridays, Sundays and off-season months are cheaper and easier to book. Ask what the venue already owns (tables, lanterns, an arbor) before you plan any decor.

9 to 12 months: book the people, choose the projects

Book the vendors who fill up first: photographer, caterer, officiant and any music. Then sit down together and decide what you will make yourselves. Our DIY vs buy list helps you sort the candidates.

A simple rule keeps DIY under control: only make things that either keep for months or take less than an hour each. Favors, table numbers, runners, lights, signs and faux flowers pass. Cooking, cakes, hair and big fresh flower installations do not.

Write your list down with the guest count next to it. That list is your project plan for the rest of the year.

6 to 9 months: test one of everything

Make one sample of each project. One favor, one table number, one runner, one light jar. You will find out how long each one really takes, whether you like the look and which supplies you need to order in bulk. It is much better to change your mind now than in month two.

This is also the time to send save-the-dates and to tell friends you might ask for a craft evening or two. People love to help when they are asked early and given a clear, small job.

4 to 6 months: make everything that keeps

Now start the batch work on projects that do not spoil. Put on a film, open a bottle and work through them:

• Seed packet favors for 100 guests cost $12 and take about 3.3 hours.
• Table numbers in cheap frames for 13 tables cost $17.03 and take about 2.2 hours.
• Cheesecloth table runners for 13 tables cost $38.35 and take about 3.3 hours.

Store each finished batch in a labeled box, one box per project. Future you will be very grateful.

2 to 3 months: the bigger builds

These projects take a little more space and a free afternoon each, so plan them for weekends.

• Copper pipe wedding arch: $215.67 and about 2 hours. Build it once at home to check that it stands straight, then take it apart for transport.
• Mirror welcome sign: $40.93 and about 2 hours.
• Fairy light jars: 25 jars for $41.25 in about 2.5 hours. Buy a spare pack of batteries now.
• Faux flower bridal bouquet: $30.06 and about 1 hour. Since the flowers never wilt, finishing it early takes one worry off the last month.

Invitations usually go out in this window too, and the RSVPs give you the final count for favors and tables.

1 month: plan the setup, not more crafts

Stop starting new projects. Instead, write a one-page setup plan: what goes on each table, who brings which box, who sets up the arch and who takes everything home afterwards. Give each helper one job with a clear start time. For the day itself, our wedding day timeline has hour-by-hour sample schedules.

Check every box against your list, count the favors, and put a small repair kit together with tape, scissors, string, spare batteries and a lighter.

2 weeks: a test run for fresh flowers

If you are doing fresh table flowers, buy one bunch of each and dress a single table at home. You will know exactly how many bunches to order, how long one table takes and whether you like the colors. It is also a good moment to confirm with the venue where flower buckets can stand overnight.

The week of the wedding

• Two days before: buy and arrange the grocery store table flowers. For 13 tables that is $212.81 and about 3.2 hours, ideally with a friend.
• The day before: make a fresh baby's breath flower crown ($12.98, about 1 hour) and keep it somewhere cool.
• The evening before: pack the car by box, in the order of your setup plan. Then stop. Eat a proper dinner and go to bed.

Prices are from our guides, checked on 26 October 2026. Twenty hours sounds like a lot until you split it: two hours on ten evenings, or four relaxed Saturday afternoons with friends.

If you are short on time

With three months or less, keep the bookings and cut the craft list hard. Pick two projects that save the most money, like the favors and the table flowers, and buy the rest. A shorter list done calmly beats a long list finished at 2 a.m. the night before. Whatever you end up making, it will be the part of the day that feels most like the two of you.
