I think I'm overthinking this but, I have received some gifts from people since FI and I got engaged, (only last week not from months ago) and was going to order some stationery from Etsy for this type of thing, and I found these, that I really love:
https://www.etsy.com/listing/156813834/personalized-wedding-thank-you-cards?ref=sr_gallery_7&ga_search_query=thank+you+cards&ga_ship_to=US&ga_search_type=all&ga_view_type=gallery are they appropriate to send for pre wedding gifts that are received, even though we aren't married yet? Or should I just go with a generic thank you card? I know this is such an odd question, like I said I feel like I'm overthinking it but I just wanted to see what others opinions were. Thanks!
