Exclusive to Dunelm, these blackout eyelet curtain linings are excellent for reducing light entering your room and help regulate room temperature leading to better energy efficiency. Available in a range of widths and drop lengths.Our ready made pencil pleat and eyelet lining kits are intentionally manufactured 3-4" shorter than your main curtains so that when they are hung at the reverse of your main curtains, the top of the lining hangs 2-3" below the top of the main curtain and the base hem sits approx. 1" above the main curtain base hem. This is so the lining remains hidden and does not hang below the bottom of your curtains.See our [linings size guide](http://www.dunelm.com/infodocs/product-info/CurtainLinings.pdf ),Professional cleaning in Hydrocarbon or equivalent reccomended.
