Weaving a Plaid Scarf

I put my lace shawl on hold til I finish my scarf which I started in November 2011. I want to wear it for my birthday on March 17th, St. Patrick's Day. I will be 53 yrs young. I am thinking about getting a better rigid heddle loom. This one was free and it is a Easy Weaver B by Harrisville Designs. I want to get one that folds. This one I can actually hold in my lap. The models I have been looking at have to be rested on a table and your lap at the same time, but they can be folded for portability with your project still on it. Not that I will be taking it anywhere, but when I get sick and tired of working on it, it won't take up that much space. I gave Ma her merino wool loopy lace scarf on Friday, February 28th. Looks like she loved it, but will she wear it? Last night I took my final pill of Coumadin. Good Riddence! 8 months of ingesting rat poison on purpose. SHEESH! I have a hematologist appt on March 6th and a venous doctor appt on March 11. They will be checking for damages. God is Great!
