PUZZLE TROUBLE

I worked on this puzzle for two days, before giving up. It was 1000 pieces, which is bigger then I like to do by myself,  I thought I could do it as two 500 piece puzzles, since the top was green and the snowman and the bottom was blue and houses. First the pieces were very tiny and they were mostly all the same shape. They did not lock together, so you could not move it around easily, and of course the edge was the shape of the puzzle. I did my usual puzzle putting together and found the snowman's face, hat,  birds and  hearts and even the houses in the bottom. but the rest of the pieces were all  red, blue and green Too frustrating, so I said this puzzle is not for me. I quit.
