Frequently Asked Questions

When does Putty beat white or gray?

On warm neutral backgrounds — tan, greige, oatmeal, natural linen — white reads too cool and bright, gray too clean and cold. Putty is the warm-neutral blend those fabrics actually need.

Putty So Fine! or Bone Glide for warm neutrals?

Putty is finer (50wt), matte, and leans beige-gray — maximum invisibility. Bone Glide is 40wt with luster and leans ivory-yellow — visible, shimmering designs. Pick by whether the quilting should disappear or catch light.

How does it behave on batiks?

On warm-toned batiks it blends into the complex color variation without tonal discord — the fine matte thread lets the print stay dominant.

Does it suit reproduction quilts?

Yes — aged, earthy backgrounds are Putty territory, and the 50wt fineness gives the near-invisible stitching that reads as hand-era craftsmanship.

Top and bobbin together?

Matching Putty in both is ideal when the backing is also a warm neutral — balanced tension and color through the whole sandwich.
