The 'Hey You' and the 'Long time no see' sentiments come from Hero Arts Darling Sentiments (331371). It is a very versatile stamp set.
The scallop circles are stamped with Hero Arts Envelope Pattern (S5507).
The Question mark is from an old Making Memories Foam alphabet set - Philadelphia
The bird stamp does not have a brand on it.
TIP :- I couldn't decide which question mark to place the bird on so this is the method I use to help me decide on placement of objects or sentiments.
I have a small piece of clear packaging that I stamp the image on.
I hold the clear sheet with the image over the card and move around until it seems OK to me. :-)
I use dye ink so I can just wipe the image off when I have finished.
The sheet sits on a shelf in front of me ready for the next time.
On to the next card.............................
