enlarging patterns

I found this great pattern in a magazine and pulled the pattern and I went to enlarge it to 200% just like it said to do then I start to piece those copied sections to make the whole block pattern. This is what I have ... how do you get the sections to stay together so you can piece the quilt block? In the past I used regular old tape but when you press it of course it melts. So ... any tips here .... can I use school glue sticks to hold the puzzle pieces in place? I just need to make this one block.

until next time ... happy quilting
