Permanent liner stains are normal and will not affect succeeding batches. It is always best to press the lightest color flowers first, and stamens last. The cotton lawn liners will require washing or replacing as they will stain and retain pollen which can transfer to your next batch of flowers. Extra liners may be purchased on our website. Liners should be hand washed and laid smoothed flat to dry. They can be pressed with an iron or misted and pressed in your Microfleur press.
