Significant Accounting Policies (Policies)	Mar. 28, 2015
Accounting Policies [Abstract]
Consolidation, Policy [Policy Text Block]	Principles of Consolidation The consolidated financial statements include the accounts of the Company and Span-Canada, its wholly-owned subsidiary. Significant inter-entity accounts and transactions have been eliminated.
Foreign Currency Transactions and Translations Policy [Policy Text Block]	Foreign Currency Translation Span-Canada uses the Canadian dollar as its functional currency. The assets and liabilities of Span-Canada are translated into U.S. dollars at the quarter-end exchange rate. Revenues and expenses are translated at weighted average exchange rates. The resulting translation adjustments are recorded as a separate component of shareholders’ equity in “Accumulated Other Comprehensive Income/Loss.”
Revenue Recognition, Policy [Policy Text Block]	Revenue Recognition We recognize revenue when goods are shipped and title passes to the customer. However, in the case of one customer relationship, at this customer’s request, we recognize revenue and title passes to the customer when the goods are produced.
New Accounting Pronouncements, Policy [Policy Text Block]	Recently Issued Accounting Standards In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, "Revenue from Contracts with Customers (Topic 606)." This ASU will supersede the revenue recognition requirements in ASC 605, "Revenue Recognition," and most industry-specific guidance. The standard requires an entity to recognize revenue in an amount that reflects the consideration to which the entity expects to receive in exchange for goods or services. The guidance is effective for annual reporting periods beginning after December 15, 2016, with early adoption not permitted, making it effective for our fiscal year beginning October 2017. On April 29, 2015, the FASB issued an exposure draft with a 30-day comment period that defers the effective date of the new revenue standard by one year. If the deferral passes a final vote, the guidance would be effective for our fiscal year beginning October 2018. We are monitoring the FASB's decision on the proposed deferral and are currently evaluating the impact of adoption of this new standard on our consolidated financial statements. Other accounting standards that have been issued or proposed by the FASB or other standards-setting bodies that do not require adoption until a future date are not expected to have a material impact on our financial statements upon adoption.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	Stock-Based Compensation We measure and recognize compensation expense for all stock-based payments at fair value. Stock-based payments include stock option grants. We have granted options to purchase common stock to some of our employees under various plans at prices equal to the market value of the stock on the dates the options were granted. New shares of stock are issued upon share option exercise. We do not have treasury stock. We have not made any stock option grants since fiscal year 2011.

Disclosure of accounting policy regarding (1) the principles it follows in consolidating or combining the separate financial statements, including the principles followed in determining the inclusion or exclusion of subsidiaries or other entities in the consolidated or combined financial statements and (2) its treatment of interests (for example, common stock, a partnership interest or other means of exerting influence) in other entities, for example consolidation or use of the equity or cost methods of accounting. The accounting policy may also address the accounting treatment for intercompany accounts and transactions, noncontrolling interest, and the income statement treatment in consolidation for issuances of stock by a subsidiary.

- Definition

Disclosure of accounting policy for revenue recognition. If the entity has different policies for different types of revenue transactions, the policy for each material type of transaction is generally disclosed. If a sales transaction has multiple element arrangements (for example, delivery of multiple products, services or the rights to use assets) the disclosure may indicate the accounting policy for each unit of accounting as well as how units of accounting are determined and valued. The disclosure may encompass important judgment as to appropriateness of principles related to recognition of revenue. The disclosure also may indicate the entity's treatment of any unearned or deferred revenue that arises from the transaction.
