Nice! Is that outdoor carpet? Did you have the pallets with the solid top or the ones with spaces between the boards? When I was younger I had my futon on two of the later type, and one of the former cut in half served as my headboard and footboard. I love seeing pallets reused -- goiod job!

Can you tell us more about how the framing would be done? Can you slope the underdeck area away from the home for drainage? CorrectDeck CX is good material.

Bought houses with Pressure treated and cedar decks. Recently changed current deck to IPE. Summary of experience & research: 1) Cedar is soft and subject to mildew. Poor deck choice. Will have short life. Eventually stepping through deck boards convinced me to replace! 2) Pressure treated: The old standard. Cheap to put in, relatively cheap to replace if needed. Vulnerable to carpenter bees(a real problem here). Being porous PT wood, accepts stain well. Can use without stain, but life shorter, greys and develops surface cracks 3) straight plastics. Best spill & stain resistance. No splinters. Get soft in high heat, high expansion/contraction with temperature can lead to sag/wavy. Need joists 12" apart or less to avoid excess sponginess. Minimum maintenance required. Like everything, color fades with sun exposure over time. Unlike wood products, can not renew color by restaining. 4) plastic+sawdust products(e.g.Trex). Stronger and stiffer than straight plastic. Originally claimed low maintenance. After class action lawsuits by deck owners, manufacturers have backed off claim. Mildew eats out sawdust leaving spongy plastic which disintegrates. Most of these products now recommend regular cleaning to prevent mildew growth. Newer versions have external solid plastic wrap to try to prevent mildew. Would not buy until at least 5 year track record of these newer products surviving without mildew or other disintegration problems. 5) IPE. Tough, strong, fire resistant, resist carpenter bees. Difficult to cut, screw(need to predrill and use stainless steel screws) increases installation work. Theoretically, very long life. Can be left unstained (like everything else, sun will turn it grey eventually). In order to keep attractive wood color, regular staining is required. Does not take stain well. Need special tropical hardwood stains. Need to restain more frequently than PT wood. Subject to discoloration by spills/stain if finish wears off or leave unfinished. 6) Other tropical hardwoods. Generally either same as or inferior to IPE in function. Worth considering if want different look than IPE.

The exact material may not be made anymore. So much has changed in the fiber business. Is it fair to assume that you are thinking of buying fabric and sewing a garment like that? There are many fabrics in the store that would be suitable for that. Fabrics are no longer given names such as "chiffon", "crepe", "poplin", "worsted", etc. Sure, you may still find some fabrics that are called by these old fashioned names, but the newer fabrics do not receive names such as these anymore. You would look in the selection for fabrics that fall into the category of active wear, or dance wear. That looks like it is ribbed. One warning, that stuff is not that easy to sew with. You don't say what your level of sewing experience is or what equipment you have. I have sewn for decades, but I don't want to tackle that stuff. I will leave that to the factories with the industrial machines that do all of that high tech stitching and use all of those synthetic threads and elastics.
