Cut Regular
Cutting a material regular is usually done when you have a directional print that runs vertically up the role, or a heavy nap that combs down the roll. If the piece of furniture is wider than the role of fabric you will need hidden seams on various parts of the furniture (Usually exterior back, Interior back and lower seat band).
 

Cut Railroad
Cutting a material railroad is usually done on non-directional fabrics or plain fabrics with little nap. It is a way to conserve fabric and longer pieces of furniture can be upholstered with no seams.
 

Requesting Yardage

  • All yardage requests are made based on plain 54” wide goods, and small prints up to 4” vertically.
     
  • If you are ordering fabrics that have smaller widths or larger repeats please refer to chart below. Start with width of your fabric then move over to repeat. Percentage is applied to amount of fabric you are ordering
     
  • Certain fabrics may not be suitable for all types of upholstery. Upholstery fabrics should have a good weight, softness, and flexibility in order for a skilled hand to produce a flawless piece.
     
  • If you are working with furniture that has extreme curves you shouldn’t use fabrics that are to heavy, or fabrics that are too stiff, and have no give. The result will be wrinkles in places that shouldn’t have wrinkles.
     
  • Heavy fabric will also have an impact on overall comfort backs; seats and arms will be slightly firmer. You can compensate to a certain extent by using 25/75 down combinations or softer foam, but be prepared for wrinkles
     
  • Heavy fabrics should not be used with higher quality downs like 50/50 & 90/10 down, the weight of the heavier fabrics will have an adverse affect on the lighter downs and will not be cost effective. 25/75 down is a good alternative for heavier fabrics
     

Velvets & Mohair
When working with velvets & mohair’s be prepared for shading. Fabrics will shade depending on what direction your viewing them from. Handprints may also be apparent. Be prepared for slight gathering along the seams that have little to no tension, for example, softer cushions with down blends. Some velvet is more crush resistant than others. We regularly finish mohair products with self-welting and it is acceptable. Please be advised when the mohair wraps around the welting the hairs will open up slightly, and the under layer may be visible. Mohair welting typically wears faster than the body. The solution would be to make all welting out of a contrasting fabric. All of our velvet and mohair products are steamed from a distance and combed before delivery.
 

Silks
Silks and silk velvets are especially hard to work with. They will typically wrinkle at the seams more than ay other fabric. This is considered natural, and is accepted as part of the beauty of these fabrics. Some silks may need to be knit backed to be acceptable for upholstery.
 

Loosely Woven Fabrics
Some fabrics that are too delicate, and frey extensively around edges. For example: some silks, or loosely woven fabrics. These fabrics should be knit backed to avoid fraying at the seams, and fabric separation during regular use. All fabrics that need backing are sent out to Keisling and Hess in Los Angeles for backing (Additional charges will apply.) Cushions will be surged, and possibly masked for additional protection.
 

Leather

1 yard of fabric – 54” wide = 17 sq. feet of leather

Average cow hide = 50 – 55 sq. feet

Estimated loss per hide = 20%
 

Print Fabrics
Be careful when ordering large print fabrics. Expert pattern matching is one of our specialties, but if we are working with a print that is off centered, and you would like us to center that print. Visible seams maybe necessary even on smaller pieces of furniture. All visible seams are matched to avoid eyesore.

Print patterns that are centered on the fabric width, and matching is continued from one selvage, to the opposite selvage, are ideal, specially when the same pattern is staggered on the left and right side of fabric width.

Be careful with alternating stripes that are not symmetrical in width or color. The best way to apply these striped fabrics is to apply lower front seat band, cushion tops, interior back and interior arms, with the correct top. Then apply exterior arms, exterior back, and bottom cushions, upside down so that all stripes match. The only time you should not apply stripes upside down is when the fabric shades (for example velvet stripes). The contrast of a shading fabric when turned upside down is too great, therefore the fabric is applied with the correct top and only the more predominant lines are matched.

When working on tufted jobs, expect the lines along the folds to mismatch. We do not match lines along tufted work!
 

Pattern Matching
Our master cutter has been trained by some of the oldest most dedicated people in the industry. The techniques he has learned a long with the incredible knowledge of how a piece of furniture should be properly fitted, allows him to match the most complicated jobs with little to no effort. We can take a 24-yard roll of print fabric; completely pre-cut a 90” loose cushion sofa, with skirt. Send all the pieces out to be quilted. Reassemble all the pieces together and have them match from top to bottom, and completely around the skirt, with little to no waste (Please refer to our pictures in our gallery to see examples of pattern matching)

Fabric Treatments
Many fabrics come with stain resistant finishes. For those fabrics that do not, various types of coatings are available (Teflon) for an additional charge. Average charge for Teflon coating-$3.00 per yard. Please look on our referral page to find an independent contractor that will come out and seal your furniture before, or after delivery. 

Laminating fabric not only makes fabrics water repellant but also makes it water resistant. The transparent film that is applied typically makes the fabric more rigid to the touch, but works great for high stain areas. All fabric is sent out to be professionally laminated.
