Track your Isacord 3350 in a free thread drawer
A free Broidry shop has a thread drawer: the spools you own, each marked on hand, low, or out. A design's thread list is checked against it, your mockups use its swatches, and the shopping list fills in when a spool runs low. This chart stays free either way.
Opens a free shop with that spool already in the drawer. No card, no plan to pick.
The Isacord pairing is Amann USA's official Madeira Polyneon to Isacord cross-reference. The Candle Thread pairing is the conversion sheet Candle Thread USA sent on August 26, 2026, and the Candle color dot is the value from their own master shade card. Madeira's spool color for this number has not been measured off their photograph yet, so no Madeira dot is shown rather than a guessed one. Search the whole charts in either direction on the Polyneon to Isacord converter and the Madeira to Candle Thread converter.
Looking for the other Madeira line? The Polyneon to Isacord converter covers this one; Polyneon and Classic Rayon use different numbers.
Amann's own Madeira Polyneon to Isacord chart lists Isacord 3350 for Polyneon 1630. Some pairings on that chart are exact and the rest are the nearest available color, so a test stitch is the final word.
Candle Thread USA's own conversion chart lists Candle 8766 for Polyneon 1630, and marks it their top match grade. That is the maker's claim about their own thread, not an independent measurement.
No. Screens are backlit and dye lots move a little between runs. The dots here are for recognizing a color, not approving one. For a logo color, or anything a customer will hold against a brand guide, stitch a test and look at it in daylight.
