This is the project I was working on in yesterday's post where I wrote up a tutorial on making paper straws. I intentionally wanted the straws to be at a diagonal, actually more of a diagonal than how it turned out.
I only used two different patterned papers and got quite a variety of designs on the straws; it all depends on how you position the pattern when rolling your paper.
The overall size of the finished heart is about 9" x 9". The red trim is from the tinsel hearts at The Dollar Tree. I just unwound the trim from it's plastic shaped heart form. Once the red trim is off the heart, you can remake the heart using twine or yarn (do a search on Pinterest for Twine Hearts for ideas).
