Hey Rick,
You're doing a great thing for your niece sounds like such a personal and meaningful touch to their big day. I’ve worked with Inscape for a few DIY wedding projects myself, so I know how tricky it can be to get all the alignment and stability right, especially when it comes to structural details like the golf bag connection and making sure the name flows cleanly with the design.
One tip I’ve found helpful is to use the "Union" function under the Path menu in Inscape to merge all the elements together once you're happy with the placement, it prevents breakage in thin areas when it's cut. Also, you might want to convert any formal font you choose into a path early on (Path > Object to Path), so you can tweak individual nodes if necessary and avoid any font compatibility issues down the line.
If you ever decide to explore other topper options or want to see how others have integrated themes like golf or custom silhouettes, this website has some pretty creative inspiration. They’ve got a mix of playful and elegant designs that could give you new ideas or even serve as a backup if time runs short.
Good luck finalizing the design, can’t wait to see how it turns out! Feel free to share your updated version if you'd like another pair of eyes on it.
