(Include a pic of your query and your question gets posted first! Email questions and pics with QUESTIONS in subject line to: boston (at) apartmenttherapy (dot) com)We sleep on a full size bed and currently have only tried full size sheets — should we move up to queen size sheets? Will the extra length stay tucked in or will it just be more material to come loose?? Is there some DIY contraption I could build to keep the fitted sheet pulled taunt beneath the mattress? I know this isn't the typical AT question but we can't possibly be the only sleep partners with this problem...right? We'll try anything!
