I have stopped using Office programs, mostly because I don't want to deal with setting up Wine. I am making a birthday card for someone, but I noticed that LibreOffice Draw doesn't have the Borders and Accents menu like Publisher does. Is there something that can replace it (website/extension/menu)? I'm looking for something like the blue and yellow block border (not very decorative).
What about a background svg image and text area(s)?
This.
If you still have access to Publisher, you can make a document that includes all your favorite border styles in Publisher, save (as PDF?) and then copy out the border images in LibreOffice.
However, there are also lots of sites where you can download free SVG background images and patterns, e.g. [openclipart.org)[https://openclipart.org/detail/260278/flower-seamless-patternremix].
