The possibilities are endless.

What goes inside an open when envelope?

It is most common to enclose a personal letter inside open when envelopes, but this doesn't mean you can't be creative. You can enclose things like flight tickets for surprise holidays, instructions to meet for a surprise event such as a concert or long weekend away. As long as it will fit in the envelope, the possibilities are endless.

Open when envelope rules

Generally there is a set of basic rules that come if giving multiple envelopes. The recipient must only open the envelopes whenever the topics apply to them. For example 'When you miss me" would only be opened when your partner is missing you and may include a letter or photos of both of you together. Another example could be for 'When you're stressed." and include a sheet of bubble wrap to be popped to relieve stress. Remember you need to be as creative as you can be.

What size envelopes should you use?

That is entirely down to what you will be enclosed in the envelopes. If it is going to be a normal letter then a good option would be a C5 envelope (will enclose an A4 sheet of paper folded in half) or a DL envelope (will enclose an A4 sheet of paper folded three times). If you are planning on enclosing bulkier items then a padded envelope or bubble bag would be the better option as these will expand and offer more protection than a regular envelope.
