When my little niece comes over she likes to take the smaller pieces and lay them out. Then she pieces them together on my used dryer sheets. They're Seventh Generation and perforated all through. When I'm done with them, I just put them under my iron rest to flatten them out. They ten to curl and you can split the sheets down the middle (3" strips). Just right for her and she whips out quite a nice size block in no time.
