Do you get everything posted in the picture?

Yes and it all came packaged in a nice box well protected.

Are the hearts removable?....and second question, can I buy replacement hearts for this product?

Yes, you basically can choose to stick the hearts inside each heart space or not. So you can easily create your own design by not filling all the hearts in if you want. If you do use the double sided tape and stick the hearts onto the backing card that comes with it, then you might have to carefully lift the heart off the card. And while we don't sell replacements at this point, if someone makes a mistake on one side, they can turn the heart over and rewrite their messages on behind. If that fails, then just paint over the heart for a different look! Hope that helps. Thanks for your interest. Regards Emma White HavenSnug

How big are the small hearts (what are their measurements)?

The small hearts are 1.37 inch (3.5 cm) wide x 1.18 inch (3cm) high. It's wider than some others so it allows for more space/characters to be put on each line.

How do you attach picture to the wooden heart in the middle ?

Yes you can. You can either put your image directly on the heart using the double sided tap that is included or use any strong adhesive. Alternatively, you can use the big heart as a template as an outline and stick your picture directly onto the backing board and use the big heart for something else. Instructions are included in the box. Thank you. Emma HavenSnug
