Please choose the correct ending to complete the given sentence: Home and Garden: [header] How to repair a snag in berber carpet [title] Look closely at the pulled loop of carpet. [step] Identify where the yarn is woven into the backing material and where it comes out to form the next loop. You may need to pull on the snagged loop to identify where the yarn goes next.

Ending1: There may also be a double loop where the hardware yarn, typically approximately the same color as the rest of the carpet, forms a final loop. [substeps] Check your materials closely, as a little color will be lost in this process. Ending2: [title] Place one knitting needle, screwdriver, or other long, thin tool through the snagged loop of carpet. [step] This will prevent you from pulling the loop all the way through the backing. Ending3: If you see broken or frayed loops, you should repair them, too. [substeps] The wrapped yarn should still have some length at the top of the loop, but you should not break through the wrap/knot. Ending4: If it seems dried, cut the excess thread so that the weave never leaves your floor. [substeps] Water stains need to be thrown out when they are all gone.
