Assemble pdf images in a downloaded sewing pattern

I am a sewer. Recently many of the pattern companies only provide the pattern using images which are configured on multiple pdf pages. Once downloaded I am supposed to download the pattern on 8x10 paper, cut the images like sleeves and garment front after assembling the patterns by taping together each of the 8x10 printed pages. The cutting and pasting is very labor intensive and when I tape the pages together there are always some alignment problems. I see a way I can assemble the pattern images before I print? If I could assemble the pieces together then I can take the pdf file to a copy service that can print on large paper.

Thank you for helping me. I am a beginner Adobe user. Downloadable patterns are a very new phenomenon for hobbyists but it looks like all patterns will move to this type of digital images. No-one wants to have to cut and paste with scissors and Scotch tape.

Thank you,

Abigail
