private and simple proposal ideas

I'm already married, but surprised my husband this evening with a little gift that got the ball rolling talking about proposal ideas. I know many women do NOT like the attention of a public proposal, so I thought I'd share our ideas (we have two friends on the verge and looking for ideas!) and perhaps help someone out!

I bought my husband a robe and had it monogrammed with his initials at Pottery Barn (about $100.) What if you got one for your lady love, monogrammed with her new initials (assuming you've talked about it, or just her first initial if not). Hide the ring inside the pocket. When she goes to try it on, just say, oh, the tag was left in the pocket. Pull it out, drop to your knee, and you're golden.

My sister was proposed to the following way: my BIL is very shy and would have died about anything public. He took every white top sheet in the house and covered all the hay bales in the barn. He even made a table and chairs out of hay bales! He strung up fairy lights (battery operated) and got takeout from the restaurant where they had their first real date. Served it all on his mother's china, with a boombox (in the 90s!) playing her favorite songs. Needless to say, my sister nearly passed out. BIL is thoughtful, but not super romantic, so all that effort to make the experience special meant so much to her - and probably cost him under $100.

Do you guys have any ideas for inexpensive, simple proposals? Let's get a list going!
