I enjoyed working the 4-in-one puzzles by Mary Thompson. She puts a lot of variety and colors into the puzzles--which also work as clue as to where the pieces fit. I was a little concerned that more economical 4-in-one puzzles might be flimsy and of lesser quality than most puzzles. This did not turn out to be true. I found them of good quality and better than a Buffalo puzzle I had. I will only buy from Bits and Pieces in the future. One addition note: I was also little concerned after reading several comments about pieces being missing from a variety of puzzles. I have now purchased and worked 10 puzzles from Bits and Pieces and luckily there was not even one piece missing. All are complete and intact.
