Hi,
ECS is closed on weekends so you might want to call them at 1-800-800-8517 on Monday to verify the DMC floss colors for this design. ECS does it’s best to have the flosses listed for every pattern they offer, but they get a LOT of patterns, so you can understand they are always attempting to play ‘catch up” on listing the flosses needed for each and every pattern.
What I did was find this pattern by the same artist and the same SKU number on a different website which I have put below. It would still be wise for verification with ECS though.
Pattern ‘model’ done on 28-count ‘antique white’ Jobelan fabric, size 9 x 13
Stitch count: 31 wide x 41 High
DMC 6-strand Floss Colors: Need one skein each
