Decor - Ideas

You can put your welcome sign on an easel, have your guest book, some floral arrangements on the table. I would keep it very simple and minimal things on the table, perhaps also include your seating chart near your welcome table

I would do a sign, maybe have your guestbook there, and have some pieces to match your centrepieces. Either the same, or bigger versions of them if you want something more grand.

Honestly, don't fret too much over it, depending on the entrance of your venue, people could already be looking/moving past the welcome table pretty quickly. Something simple, pretty, and matching your decor, will work nicely!

Something like that would be nice. Just change the flowers to the same type as your centrepieces. If you want the silver sparkle put a silver sequins table runner so you still have the white tablecloth showing.
Im having mine at a golf course as well with the same type of table as you. Planning to do something like this photo but adding candles, vases with fairy lights and some pictures to fill the rest of the table.

The idea for colour was incorporated w aterbeads of the pride flag. Each table had a different colour indicated by the escort cards.

The same idea can be done in a different manner with your colour choice.

I'm not much of an ideas person, so I just used our centrepieces on the welcome table. Our centrepieces were potted plants. I changed it up a bit on the welcome table by putting the pots into cute planters. And I had a bigger flower pot as well. I liked how it all tied in together.

It doesn’t have to be anything crazy, you can keep it simple. Maybe put another one of your centerpieces on the welcome table, then add your guestbook, a welcome sign, programs if you’re doing them, and maybe a picture of you two!

Hi. I'm no help here at all as I'm also getting married at a golf course country Club, working with a decorating co and my colors are the same as yours almost. Blush, silver and sparkling silver.
I can't seem to find a single center piece on Pinterest where I think that's the one. It's a big decision and I look forward to seeing what People suggest.
