 <p>Actually, we didn't choose these things. We went to the store with the goal to buy a few yards of fabric and a foam sheet of our choosing, but instead walked out with the idea of buying a foldable travel bed, and to tear it apart.</p>
 
-<p>The store we visited makes foldable travel beds in various sizes(personal, single, double, and queen), with each cushion joined up together with stitches. The foam is 10cm(4in) thick 1kg(2.0 lbs) polyurethane(not antimicrobial), pre-upholstered with polyester fabric(with zippers for each compartment). We couldn't choose the material, only the color(with 6 to pick from). The fabric is polyester, fine for our uses and rated for 50,000+ double rubs. We chose the charcoal-colored material(it's a bit light for charcoal, but oh well).</p>

-<p>By using the pre-made travel bed, our workload and costs for this project had been considerably cut down. We wouldn't have to sow in zipper ourselves, or to make templates(we will have to do it for the back rests, see first image at the top).</p>

 <p><b>Cutting Foam</b>. Foam stores use a foam-cutting tool that was too expensive for us to consider, others use hot knives(we don't want one). Our plan was to use a good bread knife(not an electric one), for its serrated teeth and length. See <a href="https://www.youtube.com/watch?v=xne0qjhFVNY" target="_blank">this video</a> on how to do it. But we also learned that it's possible to use <a href="https://youtu.be/rGOxj22mkOw?si=nWJEIrZ4vNN-jtgr" target="_blank">hacksaw blades</a>(this seems like the better option) to do it.<br>It is difficult for us to recommend a tool because we ended up not having to cut it ourselves, but we thought we'd mention what we found during our research. We will have to cut foam someday and we'll update this bit to say what works best.</p>
 
 <p>The cushions fit really well in our space and are very comfortable to sleep on! Next on our list is to buy more fabric to redo the back rests in the saloon, and eventually to redo all of the covers for all the foam aboard Pino(16 yards in all).</p>
 
 <p>More updates soon...</p>

 <p>Actually, we didn't choose these things. We went to the store with the goal to buy a few yards of fabric and a foam sheet of our choosing, but instead walked out with the idea of buying a foldable travel bed, and to tear it apart.</p>
 
-<p>The store we visited makes foldable travel beds in various sizes(personal, single, double, and queen), with each cushion joined up together with stitches. The foam is 10cm(4in) thick 1kg(2.0 lbs) polyurethane(not antimicrobial), pre-upholstered with polyester fabric(with zippers for each compartment). We couldn't choose the material, only the color(with 6 to pick from). The fabric is polyester, fine for our uses and rated for 50,000+ double rubs. We chose the charcoal-colored material(it's a bit light for charcoal, but oh well).</p>

 <p><b>Cutting Foam</b>. Foam stores use a foam-cutting tool that was too expensive for us to consider, others use hot knives(we don't want one). Our plan was to use a good bread knife(not an electric one), for its serrated teeth and length. See <a href="https://www.youtube.com/watch?v=xne0qjhFVNY" target="_blank">this video</a> on how to do it. But we also learned that it's possible to use <a href="https://youtu.be/rGOxj22mkOw?si=nWJEIrZ4vNN-jtgr" target="_blank">hacksaw blades</a>(this seems like the better option) to do it.<br>It is difficult for us to recommend a tool because we ended up not having to cut it ourselves, but we thought we'd mention what we found during our research. We will have to cut foam someday and we'll update this bit to say what works best.</p>
 
 <p>The cushions fit really well in our space and are very comfortable to sleep on! Next on our list is to buy more fabric to redo the back rests in the saloon, and eventually to redo all of the covers for all the foam aboard Pino(16 yards in all).</p>
