Frequently asked questions
What should I write in a wedding card for my sister?
Make it personal — recall a shared memory, tell her how proud you are, and welcome her new spouse to the family. One heartfelt line about what she means to you often means more than a long, formal note.
What is a short marriage wish for a sister?
Short is lovely: 'So happy for you, sister — wishing you both a lifetime of love,' or 'Proud of you today and always.' A brief, warm line is ideal for a card, a text, or a quick toast.
Is it okay to write a funny message for my sister's wedding?
Of course, if it fits your bond. Gentle teasing about borrowing clothes or sharing secrets growing up is warm and memorable — just keep it kind and follow the joke with a sincere line.
Should I send flowers for my sister's wedding?
Flowers are a thoughtful gesture for the couple or their new home. Local florists hand-deliver across Toronto and the GTA, often same-day, so you can send a fresh arrangement to mark the day.
