This is a row tunnel that my daughter helped me do over one of my raised beds. Only took about 20 minutes and cost about $10. Very easy to do. We used large pruning shears to cut the short pieces. Bought plastic (which isn't on yet) at Lowes very cheaply. Would like to do more of these. We just cut 12" pieces of the larger diameter and pounded those pieces halfway into the ground and inserted the ends of the smaller diameter pieces into them. Voila!
