Choosing and coordinating colours online can be tricky. I'm happy to help you match your fabrics and many companies offer colour cards of their whole solids ranges, like these AGF PURE Solids cards. It's handy to have them all in one place and which, by the way, are great for turning into magnetic swatches!
But if you only need a few and you'd like to see a fabric in person I can send you up to 5 free samples. It's also free postage within the UK! If you'd like more than 5 there will be a small postal charge. And outside the UK there will be a postage charge depending on postal zone.
